Even if i personally think (and hope) that ripple wont be around 15$ it theoretically might go that high. How many people you think hold cryptos right now? Max 1% of worlds population? Those 1% are invested in a lot of different coins right now. What do you think will happen in 10 years (by considering the growth of population) IF cryptos start to take over the current fiat share? Ripple might still be top 10 of the coins in the future since some people might want to own regulated coins like xrp. Considering this parameters dont you think this could happen?
