There's nothing wrong in btc deposits, that's why they didn't put any warning but is converting coins on this site possible?
As far as I know BK8 provides multi wallet I mean you can deposit by any available method and also request withdrawals with multiple options
For example deposit BTC or USDT we can request a withdrawal to local bank and vice versa, provided that you have made at least 1 deposit using crypto or a local bank
This is very beneficial for people who seek to make transactions with Bitcoin and then want to have some money in their banks, but one question, if a person plays there and then requests a withdrawal from the bank, does it cause problems with the bank? maybe you see someone who doesn't have a lot of money, no problem, but what about those who have or earn 1btc or more? I think there should be a maximum limit to send fiat money and to avoid misunderstandings.
