neither one of the two options you named are any good!
faucets will waste your time, may infect your computer when you visit them and they will give you such a small amount of coins that is not even worth 1 tenth of the effort you put in!
the mining "sites" are either scams or will turn into one sooner or later because selling mining contract is not even profitable for them. you will end up paying a lot more money in fees than you earn at some point. for example now that price of bitcoin has come down the maintenance fee of all the cloudmining sites is higher than their payments.
if you want to 'invest' then just do it directly in bitcoin. and if you want to earn then go do a real job instead of wasting your time. then use that money to buy bitcoin.
Helped much, thanks for this. I tried faucets and it's a total crap. It wastes so much of your time which is so precious and giving a really close to nothing return. I'm afraid to try mining sites because of the reviews available.
