I know we can deposit using btc using bnb chain, but it's not BTC, we can't deposit btc using electrum wallet to bnb chain (0x..) because of that wrong address. btc in bnb chain is called altcoin. I don't know where I can get btc on bnb chain because I just know btc (legacy, segwit, taproot)
If that means we send BTC using the BNB chain from Binance, I'm just worried that there will be problems in the future because we're sending some BTC to casino sites, especially since the government watches Binance. But indeed, we have to be smart in choosing the coins and fortunately, there are many options available that we can use to play gambling.
Binance has no such rule like that. They will not lock your account if your funds came from gambling except if your country don't allow it while you are using the local version of Binance. Binance too will not gonna waste time screen your transaction and verify if its from gambling unless it was order by the government you are residing.
Betfury is a decentralized casino, I doubt that they can determine it easily.
Some exchanges don't allow gambling funds but there is no issue with the binance.
You can send coins from the binance exchange to BetFury.io and similarly you can withdraw the coins to the Binance exchange. If you still have doubt you can read the discussion Sending BTC from Gambling Site to Binance?
