in gambling you can make 100000 satoshi in 2 minutes , but you must have experience . in any case faucets work will not be useful if you want to get massive income .
Experience doesn't matter in gambling, unless you are playing poker or sports betting. It's all about luck. You have a lot of possibilities to earn, but also a lot to lose. Faucets might not be useful, but if you are lucky, you can hit it big and gain a lot of bitcoin.
I also saw this site:
Dust Lottery; it's a provably fair game where you can bet 10 satoshi to win 0.8. If you are lucky, you might win big!
