Meanwhile, BTC is being mined normally, with 22 blocks found yesteday. But BCH remains a bottomless pit for hashpower at Multipool.us. And even worse, reward system is PPLNS so most people who invested hash power into this pool won't see any reward when a block is finally found 4-5-10 days from now.
That's because multipool mines BTC on Slushpool which has 2700-2800 PH hashrate. By mining you are pool mining with others on Slushpool as well and have a good chance of hitting blocks in a day. While in case of BCH, multipool are mining as individual in BCH network and pool hashrate is not that good against the network hashrate to get 1/day
I would say better to
1)Switch to solo pool for BCH if you are mining on a pool with low hashrate. Atleast you will have a full block reward but then again risks are very high as you may/or may not find block (depending upon luck)
2) Or, mine in mining pool with high hashrate (eg. viabtc) to have a good payout daily if you are worried about payout.
