If the ASIC miners were mining for quick profit they may have consumed a lot of buy pressure the last 6 months by selling as they mined it
If more "holder types" mine Monero after the fork it could change the price a bit, less than 5 XMR reward for each block now. The asics could have been taking up to half of available mined coins
Or they hodled their monero with plan to pump it like bitmain did with bitcoin cash and then pasted their bags to others to keep them for long period of time...Really currious to know how many xmr was mined with those asics,anyone did the math already?
