May be CW is dumping his bitcoins to try another pump of his S(V)hit, which is steadily heading towards 0
Or the usual bitmex manipulators - open short, sell on stamp; open long, buy on stamp - bart is their child
But somehow, the crooks can't always win. In the end, they get what they deserve (e.g. R. Ver and J. Wu with their flippening... errr, where is bcash now? that's right - ded forever!) The good news is that crooks always lose all their money, while those who patiently accumulate during the sideways breaks, will win the real profit. Honestly, the whales can't scare me with their dumps, nor the trolls with their going to 0 talks. I can always sell the car or other stuff and buy cheap bitcoins. And let the stupid n00bs buy my bitcoins one day above $30K, because they are so smart and sell in bear market and buy in bull market (buy high, sell low
)
