I think it is really hard to earn a cryptocurrency now, the market is going down, everything is so difficult.
If you are only seeing how to generate short term profits then you are right but if you are concentrated on getting long term profits then this could be one of the easiest moments to make money in this market since you can get almost all the coins that you can imagine for an amazing price, if you buy bitcoin now and you hold it for a few years I am sure the chances that you will make profits are close to 100%.
