If you look at XRP in long term, so you will see that XRP is the most stable altcoin (if you ignore a spike in 2017). XRP is traded at a price 0.3USD since 2017!
It has been extremely stable for a while now, which makes me believe that the coin might be controlled, because if people are putting in money, and demand is high, I dont know why the price is not increasing, I have never seen it dump for me to be thinking is the reason why it is not growing, I think that xrp developers just have to change the coin and its operation to that of tether already.
If they do, xrp will surely be the most stable coin in the market and I think that people will prefer and also rely more on it than other stable coins in the market, the only challenge would be that it will not serve as investment coin which I dont even see it serving for now because there has not been an increase at all for it to profit the investors other than the one that happened in the last bull run.
