This kind of prediction can only come from daydreamer who has never stop dreaming that altcoins will make them billionaires over night, even if xrp will climb to $100 will it magically jump from $3 to $100? They are not even hoping for the price to at least get to $10 or more before they expect such high price. Surely that's not happening in this bull season and not even anytime soon.
The big deal with XRP is the huge circulating supply. Too many XRP in circulation means less scarcity and lower market prices in the long run. The only reason why XRP "pumped" all the way to $3 was because of the prolonged bullish market triggered by Bitcoin. By itself, it won't be going anywhere.
The best thing Ripple, Inc. can do is burn large amounts of XRP to make the coin scarcer. Only then, market prices will rise all the way to the moon. Assuming demand outpaces supply. Believe me, investing in XRP is a losing game. You'll earn more by holding BTC instead. Hopefully, XRP investors are aware of the aforementioned risks before it's too late.
