Faucets are just a waste of time, if someone tries to collect enough bitcoins to be used in trading as a capital he would need to spend a lot of time on a lot of faucets and then he may get a reasonable price to start trading with.
Faucets may be a waste of time but at least you can still earn bitcoin. It may take some time to accumulate the amount to be able to trade but at least you can still trade and you have the funds. It may be small in the beginning but it will be bigger eventually if you pick the right pair to trade.
It would take you years to accumulate a decent amount from faucets that can be used as a capital in trading because the payrates of faucets are too low, even if you spend the whole day on faucets you will still not get a good amount from them for that day, they are simply wasting your time if you are targeting a capital through them.
Agree, faucets earning are too small even if you face your computer for the whole day and you gain a very small amount of bitcoins only. If you depend your desired capital on it then for sure it would take you years before you reach that amount. Its a really waste of time and doesnt worth the effort.
