I really haven’t given it much thought. Buy so far it sounds like a Ponzi scheme. Maybe fun to play with a small amounts of Vegas money. Also sounds like a place for people that want privacy for unreported income. But there may not really be privacy. Who knows? And if you doubled your money, I assume no taxes no IRS 1099 forms.
The gov’t owns the media, and if they wanted to crash it, I think they probably could with one good fake news, news story. TPTB know they over print or expand money supply too much, and crashing the bit coin market after it absorbs billions of hard earned or criminal earned dollars would enable them to sop up or mop up some excess money creation.
A similar thing happened in the 1970s when Silver went to $50. They raised rates, crashed the market, and wiped out billions of Joe Sixpack’s mattress money.
