The biggest problem for crypto prices right now (and has been for the last few months) is that there always seems to be "boogie men" hanging over the markets head... BTW I'm not saying I don't believe Tether could be a big problem, or regulation by governments and other fraud/ manipulation being uncovered.
I do believe in them things and that's why I think it so hard for investors to gain enough confidence to put a longer term bull run together right now. Just too much bad news/ possible bad future events.
