The pause of withdrawals at the shady exchange is usually a double trick...

If there are a large number of people outside the platform collecting U, then the people collecting U are most likely the exchange itself. Users have 1 million here, but when exchanged outside, it becomes 500,000, which is like getting 50% of users' assets for free...
If no one outside is collecting U inside the platform, the probability of running away increases significantly...
The exchange plays this trick itself, then resumes operations, finding an excuse that it is cooperating with regulators...
But unfortunately, users, in fear, unwittingly sell their assets (claims) at a discount to the exchange...
Back in 2022, small exchanges often played this trick before their capital chains broke. The cruelest part was that when people realized that large-scale internal fund collection was a profitable way, the exchange paused withdrawals again after a year.
But this time, the exchange no longer collects U outside the platform; instead, it splits internal assets into thousands of parts, pretending to be retail investors, offering 50% or even 30% discounts outside to transfer...
Speculators see the opportunity and rush to collect U outside, thinking they are making a big profit. But in the end, the exchange really runs away!
They exchanged real on-chain assets outside for a string of numbers in the exchange's database...
In short, no matter how this trick is played, the exchange can always take people's money. As for which to choose, it depends on whether you want to get out more or want more inflow.
