It's on the ERC20 standard, so transactions are on the Ethereum network. I use it to accumulate BAT. I have ads maxed in the settings. Then it automatically transfers the BAT to my uphold account. I swap the BAT for LTC and move the LTC to Coinbase or another wallet. LTC has very small transactions fees and confirms quickly. Once I have it where I want it, I usually convert it to BTC.
I find it is a lot cheaper to do it this way. If I try to move the small amount of BAT to another wallet, the gas fees are extraordinary. It's a lot of effort for little reward, but it is another stream of SATS.
A few years ago, this was a lot easier to hack. They put controls around it now.
Ethereum was much better when it was POW.
