SV is blasting low fee txns, ABC is not accepting them(censoring transactions?). Bitcoin.com must revert all their miners at utc 14:40. ABC chain will have higher difficulty. Reorg.
ABC has most of the exchanges so a higher price benifits them greatly. Bitmain can only mine at a loss for a very short period. Apparently they didn't have the money to pump it up?
After any pattern works for a while the bits start to pick up on it and go stop hunting. Fortunately the risk/reward is very nice on the bats so you don't end up losing much.
