If you choose to mine with Braiins Pool while using Braiins OS+, you’ll receive a 0% fee rate instead of the standard 2%. Your 100% fee reduction is given as a rebate on the 2% pool fee collected. In other words, Braiins Pool still collects the standard 2% fee at the time of mining, but all of it is sent back to you at a scheduled date each month. The rebate is distributed on the first Monday of every month.
