I think someone, probably a mainstream firm, is accumulating a large inventory of bitcoins in a methodical manner, steadily increasing the price without letting it run away, but securely holding each price breakthrough to maintain the value of their holdings.
The pattern has been consistent as the various major ask walls (88, 95, 100, 110, etc) have fallen. Buy through the ask wall, drop a good sized bid wall, let the market run with the uptrend, drop another bid wall, rinse and repeat.
Thanks - so that's a hold?
