It could be worthless or it could be tenfold or even hundredfold of its price now. If you are willing to take the risk of holding the coin then go for it but then I would advise to take profit from time to time because price is so volatile that you maybe in profit now but the next time you check it, you are already at a loss. Given the situation we have now, people are again bearish because of the break of support of $6k and some even speculate about a price of $1k for the long term.
