I think this will attract even more new investors, because they will stop being afraid of digital currencies.
Yes, you got a point, it's kinda become an advertisement for Bitcoin at all as Bitcoin is considered as "digital currency".
But the scarier here is how they will regulate their competitors, so the federal got digital currency and for sure they will attack their competitor, and here comes Bitcoin. But then again, Bitcoin built decentralized so we should not afraid at all.
