Yes you can earn enough with bitcoin if you are smart. If you had invested in bitcoin when it was new. You had now enough of money to buy everything in the world.
You can still make now money in investing and claiming faucets.
Do you mean by claiming faucets? Faucets gives us nothing but just some low amount of satoshi which is of no use for us. Even if you have not invested in bitcoins in the past, It is never too late and can be covered the profit now. Even if you are ready to purchase a huge amount of bitcoins now and hold for 4-5 years then surely you will be a millioner after 4-5 years. But it is not that easy as it is heard. Earning bitcoins is too not an easy job. You need a lot of patience for holding bitcoins for a long time.
