So congratulations!!! If you have some cryptocurrency, you are destined for massive wealth.
I just hope I don't have to kill any cops in self defense. But I suspect that when they start to drown and get desperate that they will stop at nothing to steal from those of us invested in this now. They will of course have to use the $5.00 wrench attack.
It depends upon how fast it happens. If it goes down by 2020 like you guess, it could be nasty.
A slower demise, which is the banksters m.o., means people will have time to adjust. You just might find some of those cops in cryptocurrency.
