We should be more careful in terms of ttransferring to our wallet. The same procedure applies like in a bank. If you value the bitcoins you earn, you should be more keen to details. I mean like the wallet address it has lots of letters and numbers right?
I also thank you for your answer. Yes, you are right, we must be careful (I speak for myself in this case) I already said it seems to me that it was wrong: it was my first token / btc exchange attempt (in the opposite case, I did not have these issues) moreover, no one has yet explained to me, how did they ever get me 54.3
bits in BTC following that operation: mystery?
