i am getting only 7 satoshi from faucet, is it permanent drop and will still be dropping to 1 sat? i dont think im going ever archieve that 20 sat bonus
If bitcoin goes higher, yes one day it will be 1 sat.
You can only get the 20 sat bonus if you deposit ~$50 worth of coins to your account. You get interest payments too. It is a win/win.
As well as your balance the ratio of how much you wager against free winnings is also taken into account so most people will need less than $50.
