I am not surprised. Bitcoins clogged up memory pool is being used for inside trading. He and the big boys know whats coming up round the corner -these guys know bitcoin (and consequently most crypto) will soon plummet hard - so they plan to cash out early in two or three doses. Like today, they take the first pie cash out, wait for the fish to buy in, cash-out again and again. at the end when everybody tries to panic sell, it will be mayhem, people will be trying to desperately sell coins that have already dropped 2-10x in value, but these insiders will gladly buy in with their pre-cashed funds at the cheapest prices and ultimately maintain control over the currencies. My advice to anyone is to hold or HODL (Hold+Hord) to teach any manipulator a lesson. Between now and the eminent crash, repeat these words before going to bed: "We will HODL, in the block-chain we trust, this is is crypto not your BS stock portfolios"
