Pei uses a batching system to group transactions in order to prevent our users (peitrons) from paying any Bitcoin (BTC) transaction costs.
Pei's mission is to leverage our technical expertise to make finances easier for everyone. Because of this, we developed a batch system to process payments to users, decreasing the transaction fee paid for every individual user. In most cases, you pay nothing in fees. In the rare case that there are not very many users in a batch, a fee will be assessed but it will still be a fraction of what the full transaction fee would have been.
If you decide to use Bitcoin as your withdraw method, Pei will transfer the withdraw to your wallet. Pei supports both SegWit and non-SegWit addresses. Of course, SegWit addresses are preferred.
Why transaction fees matter:
Smaller transactions are hit the hardest by fees when sending BTC. For example, it's a total of 2.4% on a $10 transaction if the fee is $0.24 cents. This fee can add up over many cashouts so lowering it for our users helps us achieve our goal of saving them the most money. You can see the current transaction fee on the BTC blockchain here as it changes over time.
