KTX × LUKKEY AMA: Two Lines of Defense for Protecting Your Crypto Assets

Summary: In the crypto market, asset risks do not come only from hackers. A seemingly ordinary link, a signature you do not fully understand, or a malicious authorization can cause users to unknowingly give up control over their assets. Once they enter the trading market, excessive leverage, uncontrolled position sizes, and impulsive attempts to recover losses can also rapidly amplify risk.

In the latest KTX Space (October 20), Mia from the KTX Marketing Team invited Jaime, CEO of LUKKEY, for an approximately 40-minute discussion covering wallet security, private keys and authorizations, phishing links, malicious signatures, DApp risks, leverage, position management, liquidation, and the psychology of trading after losses.

Ultimately, the AMA came down to two simple questions:

What permission am I giving to whom?

If things do not go as planned, how much loss am I prepared to take?

1. Wallet Security Is About More Than “Don’t Leak Your Private Key”

For many crypto users, the first step toward security awareness is simple: protect your private key and seed phrase.

That is certainly important. But according to Jaime, CEO of LUKKEY, proper wallet security should answer at least three questions:

Who controls the private key?

What exactly am I approving?

If my device is lost, can I still recover my assets?

During the AMA, Jaime explained that self-custody gives users greater control over their assets, but it also means they must take responsibility for backup and usage. One important function of a hardware wallet is to protect private keys and perform signing within a dedicated hardware environment.

LUKKEY Air, for example, is a card-shaped hardware wallet that works with a smartphone app through NFC. It uses an EAL6+ security chip to protect private keys, while signing calculations are completed inside the card. Users can view assets and transaction requests on their phones and then tap the card to complete the operation.

However, Jaime also emphasized that a hardware wallet does not mean users can stop checking their transactions.

A wallet can protect the private key and signing process, but it cannot determine what a particular signature actually means on behalf of the user.

If a user approves a malicious authorization, their assets may still be at risk even if the private key itself has never been exposed.

Wallet security therefore has two layers:

Layer One: Protect the private key.

Layer Two: Understand what you are approving.

2. Why Can Assets Still Be Stolen Even If You Never Leaked Your Private Key?

This was one of the most important points for ordinary users discussed during the AMA.

Many people assume that as long as they never give their seed phrase or private key to anyone, their wallet will remain safe.

In reality, an attacker does not necessarily need to obtain the private key first.

Jaime used a simple analogy: you may keep your key safely, but if you sign a document allowing someone else to take certain items, they may not need to steal your key at all.

On-chain token approvals can work in a similar way.

A user may think they are simply participating in a campaign, claiming an airdrop, or connecting to a DApp. However, the operation may actually grant a smart contract permission to use their tokens.

If the authorized contract is malicious, or if the authorization scope is significantly broader than what the intended operation requires, the user's assets may be exposed to risk.

Another area that deserves attention is Permit-style signatures.

These signatures may not immediately trigger a transfer or require the user to pay gas, which can easily create the impression that “nothing was transferred, so there is no risk.”

But the absence of an immediate transfer does not automatically mean that the signature is harmless.

Users should ask:

Who initiated this request?

Why am I being asked to sign it?

What can this signature allow later?

Which assets and permissions are involved?

This was one of the core messages repeated throughout the AMA: do not only ask whether you have entered your private key. ask whether you have voluntarily given someone a specific permission.

3. You See “Connect Wallet to Claim 500 USDT.” What Should You Do First?

Imagine seeing a campaign on X:

“Connect your wallet and claim 500 USDT.”

The website looks professional. It has an official-looking website, social media accounts, and detailed project information.

The easiest mistake at this point is connecting your wallet immediately.

Jaime's first recommendation was exactly the opposite:

Do not connect yet.

First, access the campaign through an official entry point that you already know and have independently verified. Confirm that the campaign actually exists.

Then compare the campaign description, participation requirements, reward source, and claim rules.

More importantly, check whether:

The purpose described in the promotion matches the actions requested by the website.

If a campaign claims that it only needs to verify eligibility but asks users to enter a seed phrase or grant an unfamiliar contract broad permission to use their assets, users should stop immediately.

There is also another common misconception:

“What if I just use a small wallet to test it?”

Separating long-term holdings from funds used to explore new applications can help limit risk exposure.

But using a small wallet does not prove that a project is safe.

The more important question is:

What exactly am I giving up in exchange for this reward?

4. You Still Shouldn't Automatically Trust a Link Posted by an Official X Account

Another common scenario involves Telegram messages.

Someone suddenly contacts you, claims to be official customer support, and even knows your wallet address and recent on-chain transactions.

Many users may think:

“They know my transaction history, so they must really be official.”

Not necessarily.

Public wallet addresses and on-chain transaction records can often be viewed by anyone.

Knowing this information does not prove that someone has an official identity.

If you encounter this situation, a safer approach is to stop interacting through private message and verify the issue through an official support channel that you found independently.

Do not use a “verification link” sent by the person, and never provide your seed phrase or private key at their request.

If someone claims that your wallet has a security problem and asks you to transfer your assets to a so-called “safe account,” stop immediately.

Legitimate support processes do not require your seed phrase to investigate a wallet issue.

And the more urgently someone pressures you, the more important it is to slow down.

The goal is not to solve the problem immediately.

The first step is to verify who you are actually dealing with.

5. “It's Just a Message Signature.” Is It Really Risk-Free?

Another situation that can easily make users lower their guard is:

“Please sign this message to verify that you own this wallet.”

There is no request to transfer funds and no request to enter a private key.

So is it safe to sign?

Jaime's recommendation was clear:

If you do not understand it, reject it first and verify it.

Normal wallet login processes can indeed involve signatures, so it would be incorrect to say that every message signature is malicious.

But users should also not assume that a signature is harmless simply because the pop-up says “Message” or because no funds are immediately deducted.

Some signatures may have subsequent authorization effects.

Before signing, users should at least confirm:

• Which website initiated the signature?
• Why is the signature required?
• Does the signature content match the operation being performed?
• Does it involve permission to use assets?

If the wallet displays a security warning, read it carefully. Even if no warning appears, that does not mean the request should be skipped without review.

There is also another easily overlooked point:

Disconnecting a website is not the same as revoking an on-chain token authorization.

If an on-chain authorization has already been granted, simply leaving the website or disconnecting the wallet does not necessarily remove that authorization.

6. From “Preventing Hacks” to “Preventing Liquidations”: Why Can Cautious Users Suddenly Become Aggressive?

If wallet security addresses the question of whether someone else can access your assets, trading risk management addresses another question:

Can you amplify your own risk beyond what you can afford to handle?

During the AMA, Mia raised a very practical question:

Why are some users extremely cautious about wallet security but willing to use very high leverage once they enter the trading market?

Jaime explained that people often perceive different sources of risk differently.

When a stranger sends us a suspicious link, we naturally become cautious.

But when it comes to a trade that we researched, analyzed, and decided to make ourselves, it is much easier to become confident in our own judgment.

After several successful trades, people may gradually turn:

“I got these trades right.”

into:

“I can control what happens next.”

And that is where the problem begins.

Before entering a trade, users should separate two questions:

First, why do I believe the market will move this way?

Second, what will I do if I am wrong?

The first question determines whether there is a reason to enter trade.

The second determines whether trade exceeds your actual risk tolerance.

Many traders focus heavily on the first question but fail to plan for the second.

They only start thinking about what to do after the market has already moved against them.

7. What Does 100x Leverage Actually Mean?

During the AMA, Jaime used a straightforward example to explain the risk of high leverage.

Suppose a user has 1,000 USDT, uses the entire amount as initial margin for a linear futures position, and applies 100x leverage.

The corresponding notional position would be approximately:

100,000 USDT.

Ignoring fees and other factors, if the market moves 0.5% against the position, the loss would be approximately:

500 USDT.

That is equivalent to half of the initial margin.

Of course, this does not mean that a 0.5% adverse move will automatically trigger liquidation.

The actual liquidation level also depends on factors such as maintenance margin, mark price, margin mode, and the platform's specific rules.

The key point is:

Leverage increases the size of the position and therefore magnifies the impact of short-term price movements on margin.

More importantly, even if your final market direction is correct, the trade may still fail.

If the market first moves against you and the position is liquidated, a later move in your predicted direction cannot reverse a trade that has already been closed.

Users can review the market through the KTX USDT-Margined Perpetual Contract trading page and should understand margin, leverage, and liquidation mechanisms before trading. KTX also provides an English guide to USDT-margined perpetual contracts.

8. The Real Question Isn't “Will I Lose?” but “How Much Can I Afford to Lose?”

So what should ordinary traders control first?

Leverage?

Position size?

Or emotions?

Jaime's answer was not to focus on a single variable, but to start with a more fundamental question:

How much am I willing to lose if this trade fails?

Establish that boundary first.

Then determine position size, exit conditions, and whether leverage is appropriate.

Do not open a position first and only decide how much you can tolerate after the position starts losing money.

Instead, define rules in advance:

Under what conditions will I exit?

When will I pause trading?

Should I stop after a certain number of consecutive losses?

Am I allowed to add more funds temporarily?

The value of these rules is that you make decisions for your future self while you are still in a rational state.

Stop-loss orders can be useful risk-management tools, but during extreme volatility or when liquidity is insufficient, actual execution prices may differ from expectations.

Therefore, a stop-loss price should not be treated as a guarantee that losses will be capped at exactly that level.

9. The Most Dangerous Thought After a Loss: “I Have to Make It Back”

After losing money, many traders experience a powerful urge:

“I have to make it back on the next trade.”

The problem is that once the next trade carries the additional mission of recovering the previous loss, it is no longer simply another trade.

It can become:

“I need to prove the last trade was just bad luck.”

“I need to recover my account.”

“I can't finish today with this loss.”

But the market does not operate according to your need to save money.

Jaime suggested a simple self-check:

If the previous loss had never happened, would I still take this trade?

Would I still use this position size?

If the answer is no, it may be time to stop.

During the pause, traders can review the previous trade:

Was the market judgment wrong?

Was the position too large?

Was the exit rule not followed?

Or was there no clear plan in the first place?

There is also an important distinction:

Planned position scaling is not the same as repeatedly increasing risk after a loss.

The key questions are:

Was there a clear reason to add?

Was there a predefined maximum risk limit?

Does the original trading thesis still hold?

If these questions cannot be answered clearly, preserving capital may be more valuable than rushing to recover the loss.

10. Five Rules for Combining Wallet Security and Trading Risk Management

If the entire AMA were condensed into five recommendations, Jaime's answers would be very clear.

1. Understand and protect your recovery method

Understand which wallet model you are using and what recovery materials you need to keep safe.

Never give your seed phrase or private key to customer support, websites, or campaign organizers.

2. Before every confirmation, understand what you are actually doing

Connecting, logging in, authorizing, and transferring are different actions.

When an operation involves asset permissions, carefully review the target and scope.

3. Give different types of funds clear boundaries

Long-term holdings, daily-use funds, and funds used to explore new applications can be managed separately according to your situation.

Before trying a new application, decide how much you are willing to put at risk.

4. Determine your acceptable loss before deciding your trade size

Do not skip risk budgeting simply because you want higher returns or believe your capital is too small.

For derivatives, understand margin modes and liquidation rules before trading.

5. Give yourself time to verify and pause

If you do not understand a signature, you can simply choose not to sign it.

If you find yourself thinking only about recovering losses, you can choose not to trade.

The logic behind these five recommendations is consistent:

Do not let someone else rush you into giving away wallet permissions, and do not let your own emotions push you into taking excessive trading risk.

11. Six True-or-False Questions: Do You Really Understand Wallet and Trading Risks?

During the final rapid-fire segment, Mia and Jaime summarized the entire discussion through six statements.

“As long as I haven't leaked my private key, my wallet is safe.”

False.

Malicious authorizations and signatures with authorization effects can also put assets at risk.

“A link posted by an official X account is always safe.”

False.

Official accounts can also be compromised. Users still need to verify the link and the requested action.

“Connecting a wallet is just logging in, so there is no risk.”

Not necessarily.

Simply connecting a wallet does not normally grant token transfer permission by itself, but subsequent login signatures, authorizations, and transactions still need to be checked separately.

“A cold wallet means 100% security.”

False.

A hardware wallet can strengthen private-key protection, but users still need to back up their recovery information and carefully review authorizations and transactions.

“If my market direction is correct, 100x leverage is fine.”

False.

The market can move against the position first, triggering liquidation before the predicted direction eventually plays out.

“Adding more to a losing position is always reasonable because it lowers the average cost.”

False.

The key questions are whether there was a predefined plan, a maximum risk limit, and a trading thesis that remains valid.

12. Conclusion: True Security Means Keeping Control in Your Own Hands

The KTX × LUKKEY AMA moved from wallet security to trading risk management. While these may initially seem like two different topics, they ultimately point to the same principle:

You should keep control of your assets in your own hands.

Wallet security asks:

What permission am I giving to whom?

Trading risk management asks:

If things do not go as planned, how much loss am I prepared to take?

A user can have a highly secure hardware wallet and still face risk because of a malicious authorization.

Likewise, a user may never encounter a hacker but still lose a significant amount of capital because of excessive leverage and uncontrolled position sizes.

True crypto asset security therefore is not simply about buying a hardware wallet or setting a stop-loss.

It is a set of everyday habits:

If you don't understand the link, don't rush to click it.

If you don't understand the signature, don't rush to sign it.

If you don't understand the authorization, don't rush to approve it.

If you haven't thought through trade, don't rush to open the position.

After a loss, don't rush to get it back.

At the end of the AMA, Jaime summarized the discussion with a simple message:

Check the authorization before every confirmation, think about your exit before every trade, and keep control of your assets in your own hands.
