if there is a faucet that I take it and then put the rate of 2% to win and do it in a loop until you win
It is a safe methods to gamble you do not use your money, but you play it from faucets
I think do not have risk if you have loss of bitcoin in gambling.
In my opinion, even faucet money also will not be giving us a safe gambling as it may induce addictions towards gambling. After many betting with the faucet money, you may tend to use your own bitcoins to bet more to win quickly which may leads to losses later.
