I Think the banks and others in power may have actually caused this last “crash” so they could get a lower cost foothold.
I think the banks and governments are concerned about what crypto and blockchain ultimatly means to them (loss of control)
I am also not completely convinced that we are out of the woods from a crash stand point, there are some people or probably entities / groups that have large amounts of funds that are triggering mass almost instant sell offs in the billions (just happened late last night goin from 520 MC down to 490 in less than 30 min). People like me who have a very small stake in this game are very much at the whim of a few I fear.
Long term, I think this will all get worked out, as more money comes in the volatility and spikes will smooth out. As more people use these for every day applications it will stabilize. So to your point, now is a great time to get in the game !
