You can't do any investments with 0.02 btc, that's too low. Just gamble it for x2-3 profit.
Gambling is not good choice, too risky but if you're lucky guys ever, i can't forbid

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.
you can buy a forum account with your .022BTC, a member rank i think and you can earn .02BTC+ per week in a signature campaign
Thanks for trying to help the beginner instead of like the rest just telling him "LOL NO TOO LITTLE BTC TO INVEST, NOOB"... this forum some times makes me laugh.
Actually if OP can't wait for rise he's rank and want to more profit for enrolling in sig campaign, buy an account is the solution(also don't forget to use escrow).
