The problem I see with BitConnect is that earnings from investing in bitcoin are never guaranteed. There are also lots of one coin seminars too, where they propagandize about guaranteed income, but that doesn't make one coin any less a scam. However, it is a good point that as long as speculative interest in Bitcoin remains high, everything, scam or not, will prosper. Nonetheless, the scammers are probably the ones who are truly partying in the USA right now.

I'm not saying those earnings are impossible to get in the current market, only those kind of results generally come with ample amounts of risk. If BitConnect was a Bitcoin hedge fund seeking to get those returns, I would be less worried.
