Well, i think it wont affect bitcoin in anything, amount or price wise.
Because it is just like a normal buy and sell things, and that is what happen in an exchange everyday. It is just a cycle.
But for the transaction matter, there will be a lot of transaction if this happen, and the question is, can all this transaction be done in a fast and short time? This would hurt bitcoin names if the transaction is slow, as people want for faster and safe transaction with digital currency. So because of that, i would love to see bitcoin has a fast transaction (maybe instant would be better) with an acceptable fees.
