The "walemo" pool is scam. The report states that it was paid twice in 0.5, but nothing came to the wallet (even after hours). And very little efficiency. Be careful.
We have to warn other users about this. But make sure the reason you are not seeing your balance is due to the wallet restore height in your GUI wallet is not set to 0. If so refer to this : https://github.com/Tesoro-Dev/tesoro-gui/blob/master/README.md
