The user in question is definitely a SCAMMER. I contacted the user to ask for an exchange and he sent me wallet screenshot which is the same identical to the one posted by vareole in his channel. I remember that vareole is a SCAMMER. So either it's the same user, or the OP has copied the screenshot of vareole wallet and passes it off as his. Either way, it's definitely a SCAMMER. I don't recommend trading with the OP.
