After so many years in the crypto world, the worst thing I've seen isn't liquidation, but having money in your account that you can't withdraw. $ETH

A brother turned a few thousand USD into over 400,000. $TON
Screenshots posted daily, and the next day the card was directly frozen, with both the bank and the police conducting dual checks.

Explaining the source of funds and providing additional documents, half a month later, the person had lost a lot of weight.
Many people only focus on market trends but overlook a more realistic issue:
Bank risk control is faster than market fluctuations.

Once the system determines "abnormal fund flow," it can lock your card within minutes.

I’ve also fallen into this trap myself, and I only remember one thing afterward:
Making money is for apprentices; securing your gains is for masters.

Three pieces of advice, all learned from lessons:

First, don’t withdraw all at once.
Withdraw in batches, control the pace, and avoid large sums entering or leaving in a short period.

Second, the fund flow must be clear.
Use compliant channels for deposits and withdrawals, keep good transaction records and bank statements, and be able to explain the source.

Third, account separation.
Use different cards for daily transactions and withdrawals to reduce risk exposure.

Remember one thing—
Making money depends on ability; securing your gains depends on awareness.
