Ripple could be at $5 in 5 years. The fact that it is not growing like the other cryptos is because Ripple does not lose its hold on mining XRP tokens. Ripple Labs takes a majority of the stake in mining XRP tokens and until it gives that much stake to the people, it will not grow. Besides this, people are looking for other cryptos that are booming in the market like Litecoin, Ethereum, Cardano, and many more. Ripple stands no chance to beat them at present because it is not performing well for the last few years. Still, it can grow with time.
Unlike many ripple predictions this is not so out of place, a price of 5 dollars is reachable there is just one big problem, the SEC, as we know there is an ongoing investigation against ripple and until this is resolved I do not think we should expect any significant growth, and if things go badly for ripple I think it will come the time in which we will begin to question whether ripple has any chance to last those 5 years, some people may not believe this to be possible but we know that altcoins can collapse in a matter of months and this could be the case for ripple if the result of that accusation goes against it.
