Only the BTC portion of it remains intact, although still in a loss position.
Tron is an interesting coin, but Justin Sun seems like a complete huckster, a snake oil salesman. Sometimes a coin with real utility can overcome its origins, but I don't know about Tron. If you're still holding any of what you bought two years ago, you'll probably be waiting a long time just to break even (IMO).
Bitcoin is another story, though. Even if you bought it at $20k, I wouldn't dump it now and cut your losses on it. I do happen to think it's headed higher, but it has to break through the $10k barrier first before it starts approaching a new ATH. That could take a while. In any case, think of your experience as an education--even if it was an expensive one. If you learn from your mistakes, hopefully you'll be less likely to repeat them next time a bull market rolls around.
