Tether blocks USDT. Here is a real example of a loss of $ 301’000 due to USDT blocking.

How to check the USDT Block?

1.Follow the link
https://etherscan.io/token/0xdac17f958d2ee523a2206206994597c13d831ec7?a=0x087a39ecd3e12db24b76025efaf077a2fd6e44c2#readContract

2. In the field No. 18(isBlackListed) enter the address and press Query

We look at the result, true - the address in the blacklist, fals- clean. If the address is in the black list, then the USDT on it is frozen and it is no longer possible to send them anywhere.



Tether ( https://tether.to/ ) may block your USDT  at any time.

Wow, right?
And no one will explain to you the reasons for blocking

But this is only the beginning, I began to study this issue in more detail and found a lot of useful information.

Almost all stablecoins can be blocked.
At the moment, only DAI does not have a blocking function and USDT-Liquid (but did not find who uses it).
