1. So i read that if i'm only using faucet and don't play multiplyBTC or buy lottery tickets then my faucet reward would go down. Is it true?
Yes.
If so, what percentage should i keep all the time to remain the same faucet reward (right now it's 6 Satoshis) forever? Is 5-10% gaining back every day enough to not lose those 0.002$ per roll?
It's a game so you have to work out the wagering requirement yourself.
No. It doesn't say it is a deposit requirement. It is a wagering requirement that is proportional to your free winnings. You have to wager enough compared to what we are giving you for free on an ongoing basis to earn the bonus wagering bonus.
