I don't think the issue of CoinBase has finished yet as their clients are not happy to wait for four months and I understand them bearing in mined that Segwit2x agreement was decided in mid May in New York and took two months and a half for a process to get implemented without knowing about the result and now CoinBase needs four months to do what all other miner and exchange did in two months and half. Doesn't that seem doubtful to you?
