Actually I like your idea, but I don't know how they could manage such multi currency in one block chain. Actually I am not a technical guy so no way to say anything...
Anyway your idea seems great and they way you describe about the practical problems I am really like that. Thank you very much for this valuable post!
really appreciate your effort!@kevinwong,
Cheers~
Lol i have no idea as well. Side-chains and all that magic. Well if its a technical thing, I believe it can be done!
