Sometimes people want to invest in crypto currencies but they are little skeptical about it and do not want put their funds in cryto currencies with all the FUD surrounding us.There is also possiblity that you want to invest but you are running low in funds for investment.
So here are some of my suggestion to earn some crypto currency.
3. Bounties and Airdrop.
If you are not able to fit in any of the above ctegories then you can try Bounties and airdrop. But accept bounties that pay some established crypto currencies.
I prefer to work on number 3 and Bounty is my choice.
As for the airdrop I didn't like it because Airdrop only wasted my time working on the Bounty Campaign.
