keep for 5 years and you will see the difference

$XRP Since I first learned to play with cryptocurrency, I have considered this XRP coin to be the currency of the future, with a purpose and a strong community foundation and a robust market capitalization. Whether it goes up or down, and even when it dropped below $2, I still believe it will soar beyond $4. However, for more than half a year now, my patience has reached a point where I don't know if I should keep it or sell everything. I am holding 1000 XRP. Everyone, please give me advice: should I hold on and wait longer or sell everything?
