If you can't wait anymore, you can sell it now as long as it has given you a profit. Then you can invest it in more promising coins. But, if you plan to hold it for a long time it doesn't matter either, we won't know what happens in the future. Maybe the coin could soar.
Profit or break even.
There are holders that selling even at break even because they just want to take back their original amount or even with a little cut loss. They've seen another crypto to hold.
Like for those who have been holding massive altcoins, if they're at a little loss, it's better to do that and choose another better crypto to hold.
