During these hard days I'm trying to buy solid token projects that are very cheap but price continues to go down... I am very sad for this 
Why are you so upset? I think a bad experience should also be. I started learning trading from a cryptocurrency market, and I discovered a lot of new things. One of this is that there is no bad market, inexperienced traders exist. And besides, you bought your position in the flat, and not at the peak at the end of last year. You just need to wait for a favorable moment.
