About the Ethereum Basic? I have no idea what is this about. Clueless :-P
Ethereum Basic team also offers cryptocurrency users to get their coins after the user integrates their ETH wallet into their website.
What do you mean integrates? Giving them private key?
Most likely that way. Ethereum Vision had the same scheme.
