Investing your money in the market is dangerous. You can go bankrupt. It is best to take a bounty or participate in the distribution of tokens. The market situation doesn't make good money without investing.
Bounty, Airdrops as well participating in some crypto events and activities, but now that the market is just recovering doing plain bounties is not that profitable, it will be good if you have something you can really offer like being a blogger or website that have many followers.
