you can earn from faucets,signature campaign then let's say u have 0.01 for example u have 3 ways
1.invest in investment sites but i don't like that way lots of scam
2.gambling/games good & fast but too much risk u may loose everything &start over
3.trade on exchanges look for coins low in price,have high volume|& u expect it go high
I would do this, but only certain ones like that have been around.
Like this person who mentioned faucets it should be legit ones like freebitco.in. And anything else consider in the btc community you should eye on if its been around more then 2 years to qualify its safe.
