Cooperating with main Bitcoin pools, we provide a transaction accelerator service that speeds up transaction confirmation. Due to Bitcoin frequent congestion and user’s low fees, some transactions have not been confirmed yet. The acceleration service is to help users speed up their transactions – take the blocks in our pools. Before sending transactions, we recommend you to check, the current best rate, and then set appropriate tx fee to enjoy the normal bitcoin network confirmation. Regarding that Pool is using FPPS mining mode and those accelerated transactions are with low fees, pool will subsidize miners to ensure that their earnings are not compromised.
