Which coin did you buy? Because with the current crash, prices are very low and you can make profits in the long run.

I made a mistake, I was on the purchase page and I placed an order thinking I was selling all my shares. I had made a profit, but when I realized that I had not sold but bought with all my reserves, now I am at a deficit, not huge for the moment, but what do you think, should I sell or wait to return to 0 for the last purchase by mistake?
