So it is, Binance is extremely sensitive to new ip addresses and device changes, as well as to any conversations since support regarding changes to account security data. My account was banned twice in 3 months.
1 time, when I decided to try to log into my account from a mobile phone, and the second time I wrote to technical support and asked: Is there such a possibility to replace the mailbox with another one? I was told that it can be done. This ended the conversation, and after 5 minutes they blocked the withdrawal of funds from the exchange, saying that I was conducting extremely suspicious conversations and the account might have been compromised. So with technical support, need to be careful. Anything you write can be used against you.
Okay, on the one hand I understand any possible frustration caused by such a move, however, on the other hand it was done for safety reasons and not in an attempt to mess with its users. Imagine if your account somehow got compromised and ended up with your money. I generally never had any negative experience with Binance, except from their KYC and the constantly decreasing yield from staking and savings.
If you are using them to store your money, then I would say that it is a bad deal to do KYC just because of that. My reason for using them is simple; since I already did KYC, I might as well use their debit card to spend my bitcoin in an easy and convenient way. But even then, I am aware that every time I send bitcoin there is that I may lose it so I only send smaller amounts, no more than I spend in a week or so.
I never had any money in exhanges the past few years, for the obvious reasons. However, it was the easiest and fastest solution to generate a minimal income after Terra USD crashed.
