I remember when BCH first came to life and some folks claimed that some sort of "flippening" will happen, BTC would be dethroned etc. Just the thought of this nonsense still makes me giggle. Now watch what is happening to it. Gotta love that comedy. I love crypto for keeping me high-spirited like this.
Nchain/Coingeek has partnered with squire which has a partnership with Samsung. They will be rolling out the most state of the art asics, once ABC and opposing factions on BCH are forced off the network, they plan on producing asics designed to mine every POW algorithm. They will begin with the alts, destroying their networks and selling any coins mined for BCH. From there they will move to BTC. Forgive me if my technical verbiage is wrong because I dont know much about this but I read somewhere that the original satoshi opcodes will be enabled during the upgrade, and using those opcodes CSW will be claiming the satoshi bitcoins. I dont think this is a bluff, just look at cash.coin.dance
They have the least amount of nodes but the most hash rate. All the reading and research I've done is telling me this is not a bluff. I truly believe we will see the end of all alts in the near future, and the flippening of BTC to BCH after.PoW Miners can't mine coins not based on PoW.
Meaning any PoS consensus or alternative consensus Altcoins, is literally out of their reach.

FYI:
They Can however kill Ethereum PoW coin , and in doing so Wipe out every Eth Token in 1 fell swoop.
Ethereum is already unprofitable even before their
shark attack.

As time progresses I feel that there will be an increased crackdown on them and exchanges selling them. Or, there is the possibility that if and when the market explodes again people will want to experiment with shitcoins for quick pump and dumps
