Hello from India,
i am new on this forum but i have been earning bitcoin from faucets over last year.
i have 0.022 BTC with me , i hear a lot of people saying to join campaign how can i do that , i have 0.022 BTC want to invest to get profit, please help me.
The safest would be something like HaoBTC, which pays interest on BTC that's deposited (and lets you withdraw it at any time -- interest is paid hourly). Eric is pretty active on these forums (he works for HaoBTC) as well.
a centralized third party is never safe. search for decentralized, interest paying alternatives. (eg. BTS, NXT Assets).
