The supply of Ripple is many many times greater than Bitcoin. For Ripple/XRP to reach 200$ the marketcap would have to be in the 100 Trillion range. This would not be happening even if banks poured all their money in Ripple. 1$ might happen, but even this needs a very signifanct market cap increase given the huge supply.
Even that would be a multiply by 5... And you have to mention, the maximum amound of ripple is always getting smaller.
International transactions 180 trillion happen every year. If all these transactions starts taking place through ripple. You never know what's gonna happen.
