If I was on your shoes I would probably sell Terra, I know that people have great expectations out of this coin but at least to me it seems to be overvalued at the moment and it could be a good idea to get out of it while you can and invest in a safer coin like bitcoin, or maybe you could take a risk with a new altcoin and in this way to try to grow your profits even further. And about the second coin I will probably get rid of Avalanche as the other coins are simply better in my opinion.
