I think $50 by the end of the year would be a more realistic prediction. That is if the market continues to be bullish.
Yes, 50$ would be a good price but it also depends very much on market.
Right now, Avalanche is at 60$ and maybe it can get even a higher price when more updates will be published, like subnets for Avalanche or an update for lower fees.
While Bitcoin is very high currently, if Bitcoin drops Avalanche will most likely drop, too.
