$100 for 1 ripple is very crazy in price and definitely requires so much marketcap.
We must think realistically and positively so that we also understand what the prediction is relevant.
But in Cryptocurrency nothing is impossible because Bitcoin also no one knows that the price of 1 Bitcoin can penetrate the number 69,000 USD.
If you think positive also for this ripple coin it looks very clear from the total supply circulating and that is so much value, when compared to Bitcoin which is only 21,000,000.
