After the BCH hash war is over, he will attack bitcoin.
It's disappointing actually, we haven't seen much of a hash war at all. These suckers contacted nearly every miner, even Roger, hoping to rent mining gear to make themselves look like they are capable of messing things up.
In total, and it's probably way more than what they really have, they account for 2EH. Most of this hashrate belongs to Calvin Ayre, and he will eventually run into problems with Craig Wright, and it will result in another fork.
It's just a matter of time before Calvin either forks off, or points his hashrate to BTC or BCH. Craig Wright as silly as he is with his fellow nChain losers will be left alone for ever. nChain itself might fork as well.
