To use free earnings to gamble at FreeBitco.in isn't a good idea in my opinion. You will need to claim a lot until you have a decent bankroll to start gambling, unless you are very lucky and hit some nice prizes like 0.002-0.02 BTC.
It doesn't worth the risk to play with a small bankroll. You won't make much profit and you will be risking your money a lot with high house edge...
And then, all your progress claiming satoshis for days, weeks, months will be over. Better to let it generating passive income.
If you do handle this way then you are just totally wasting up your precious time on accumulating faucet just on tending to play and hope for hitting up jackpots. Slim chances but there are people who did it actually but we should not think off that we would hit those numbers because this would really push you harder and totally wasting up your time on claiming and soon you will waste it out for a couple of bets which isn't really worth at all.This is a normal thing to happen but yet people still love to claim faucets and I don't know why.
Lotteries in general give even lower chances to people hit a prize and people still play it in a daily/weekly basis, so I think it worths a try at FreeBitco.in's faucet every hour. It's free, has better chances than lottery and I just need to click once at roll button... The only thing I regret is about not using this faucet more frequently years ago when the rewards were higher. Comparing those rewards to currently's BTC price I would have made a lot of profit.
Now I try to enjoy maximum as possible because BTC can skyrocket in the future and these earnings from faucets, even if not jackpots, will worth a lot.
