That is the reason you should try signature campining, but you need a good account for it. ( i mean with good rank of course )
you just better buy some btc and invest them, or trade btc/usd or any other alt/btc
not really, if you play bitcoin faucets, yes they are really waste of time, but if you play altcoin faucet, i think you will get good chance to selling it to get bitcoin and then convert it into fiat so you still have chance to earn money with bitcoin.
People always like finding ways of getting money quickly. It is good to be ambitious, but whatever you do should start somewhere. The richest people in the world never became rich overnight. They had to start small and grew their wealth to what it is now. similarly, with bitcoin, you can start small and grow slowly. Therefore, there is no problem with starting with the faucet to earn bitcoins. Telling a newbie to earn through signature campaign is useless.
