A lot of them I used to try were mostly to quickly raise your level on faucet hub-back when they were operational-but they paid pretty bad compared to traditional faucets.
One of them, firefaucet, keeps erasing my balance after I go a period of time without using them-and they always seem to be out of funds for withdrawels anyways. So it's not worth my morning or nightly routine.
I am not familiar with express crypto. how does that pay compared to say cointiply or bonusbitcoin?
