Learn and try to join several airdrops. Airdrops are free to join with no risk.
I would also recommend that you join a few AIRDOPS. This will bring you some coins and may be your starting capital. But I would also advise you to invest some money in the ICO. I think it will bring a very good profit after a while.
Yes you can do airdrops if you are new then while waiting for the airdrop to come ion your ERC20 wallet, I suggest you have to start your own search very well, study about cryptocurrency and blockchain technology how they works and how they will be the future technology of our world.
