You should never use the GOPAX coin exchange.

I occasionally need to trade coins, so I manage my funds using accounts across several different exchanges.
GOPAX is absolute garbage.
You might ask why I use it when Upbit and Bithumb are available,
but there are times when it is necessary.
However, they suddenly blocked more trading and even froze withdrawals without any prior notice.
You should never use an exchange like this.
I am posting this so that no one else becomes a victim.
