I don't know a great deal about crypto. I'm fairly new to the game. I do like the 'Steemit' platform - the gamification, if you will of building crypto, however, like yourself, mainly use SteemPeak, for many reasons.
I guess that if STEEM were in a bad way, then it would be the only one nose-diving. The fact that they all are probably points towards more of a loss in confidence of crypto across the board rather than just one or another. I'll be sticking with STEEM because the only STEEM I have is what has been awarded me via posts and comments, so it's a risk free investment.
You'd be pretty annoyed right now if you held Bitcoin and didn't cash out back in January.
