No matter how much you earn in the cryptocurrency world, if you can't safely withdraw your funds, it's all for nothing.

In recent years, I've seen too many tragedies of 'account freezing and bank card locking':

A friend of mine made a tenfold profit during this wave of bull market, but when his card was frozen, the customer service said 'suspected of assisting in an investigation', and he hasn't recovered a single penny for three months.

He's not involved in any illegal activities, nor is he laundering money; it's just that there was a problem with his withdrawal method.

Now, let's highlight the key points: 90% of people have fallen into these traps:

Using OTC to buy coins and stepping into the money laundering chain, getting caught in the crossfire.

Transferring immediately after a large amount is credited, the system deems it as cashing out.

Mixing main cards with cryptocurrency transactions, and when one gets frozen it affects daily life.

How to avoid these traps? Here are five rules:

1. Prioritize mainstream platforms:

Only use reputable exchanges like Binance or OKEx for withdrawals; don't engage with obscure platforms.

2. Minimize USDT withdrawals:

Risk control focuses on this, try to convert to BTC/ETH for withdrawal to avoid scrutiny.

3. Use dedicated cards, don't use your main card:

It's recommended to prepare a 'sub-card from a local bank', solely for deposits and withdrawals; don't mix usage.

4. Don't rush to transfer after receiving funds:

Wait at least 24 hours after the funds arrive before transferring out to avoid 'quick transfer' risk control.

5. Avoid executing transactions at odd hours:

Try to withdraw during weekdays between 9:00 AM and 9:00 PM, avoiding peak times is much more effective than trying to push through.

What to do if your card is frozen? Don't panic:

First, observe for three days; it may be a temporary hold.

Inquire with the bank to find out which department froze it and which case it relates to.

Prepare on-chain records, transfer screenshots, and chat logs.

Actively cooperate and explain that you are a legitimate trader.

Many people have their cards frozen not because they broke the law, but due to insufficient evidence, causing them to panic.

Remember, only the money you can safely withdraw is truly earned.
