I tried to send 0.067 BTC from BTC.com and the fee is 0.011? I didn't expect the fee is 15+%. Is it right?
Well btc.com is part of the company that charges the highest mining fees of all the pools, so I'd not be surprised if they do other things in the worst possible way ...
Actually the fee's do not go to BTC.com. 100 percent of the transaction fee's go to the miners. There are three different selections of fee's to choose from. Optimal,low priority,and accelerated priority. Optimal is the most expensive. Low priority is the cheapest. And the accelerated priority is they include your transaction into free mining payouts when they find a block.
Xuy, if you want cheaper transactions. Use low priority.
