Somewhere around, I don't remember if it was on Steemit or another of the Crypto Social Networks, I read an article which basically stated that the current increase in prices of Bitcoin was triggered by a mystery buyer who bought somewhere around $100 million worth of Bitcoin.
Of course that someone believes in Bitcoin so much as to invest that kind of money can only be good, but is the market so fickle that a splurge worth maybe 0.15% of the market cap can make the market cap go up over 15%?
That means that for the smaller crypto's in the emerging Crypto Social media only a relatively small investment probably a few tens of thousands of dollars could trigger a bull run. I believe this is one of the things that is problematic and liable to make people stay away from crypto, it is just to easy to manipulate the market.
