How long do you think I would have to wait until I break even or see profits? I bought nearly all my coins near ATH, unfortunately.

Could be today, tommorow, the next after tommorow, weeks, months, or even years. No one know exactly when the price will be back or recovered. It's hard choice anyway, you could just cut loss and re-invest on other token or let your investment stay like that for longterm
Yeah or it could be never, most startup in real life will fail and only a few will succeed. I believe we are in a bubble like the dotcom bubble, only a few good coins are going to be the next amazon.
