Someone used Cryptopia's address instead of their own address, because there was a payment of 1.0400515 from the pool directly to Cryptopia (edf2d63cdf0b6275ead22c9e6d66aa8ea31dc0ccb367fad2e7c08a25) included in block 537311 (2018/03/02,03:37:18) - if this is you, you need to use your own wallet address.

If you have low hashrate, then it may take several rounds before you get a payout because the minimum payout is 1 Bismuth. There are people mining with 300 MH/s who only get about 1 payment a day, but most people have much higher hash rates, so get paid every round.
