If we talk about the easiest way to earn money in crypt, then this is definitely airdrops. Because you do not risk anything, but wait for tokens or coins will not be less than a month
I'm sure that the best thing now is to invest in the Ethereum and the fact that it is still less in price than Bitcoin plays for the benefit of small traders. I'm sure that ETH will someday overtake BTC.
If you are not sure of your strengths or just a newbie in trading, then you should not invest big funds at all. I think that you can return this money with a long-term investment in the Ethereum.
