So now it can be 100% confirmed that bitcoin gold BTG is a completely & purely Chinese pre-mined ico scam.
No, I don't think this is right. The guy is purporting to be a BTG Lead Developer. It is not 100% confirmed, until we see a statement from Bitcoin Gold website. Maybe there is some truth there, but there's usually a lot more to the story than what we're led to believe. P.S. There is a lot of guys trying that trick on this forum. It's a simple copy paste script. Hardly think people like that would deserve to be lead developers of a Bitcoin fork.
