So they are getting in now, I hope with their entry many more will follow and hopefully they will stay for good, Cryptocurrency really needs this kind of investors, without them Bitcoin and other cryptocurrency will have a long bear trend.
institutional investors enters with a back up plan or exit plan, what when they will leave??
unless you think the whole bitcoin price is because a bunch of imaginary investors bought it, their imaginary exit won't have any effects on anything!
it is a market we are talking about and there is demand from a lot of different sources, from multi millionaires like Warren Buffet, to newbie investors buying $10 worth of bitcoin. the total result of millions of investors make the current price.
