Yeah it would effect Bitcoin somehow because many of the Bitcoin users sell there Bitcoins against the US Dollar, so know they will have to fgind a other currency to sell for.
I think that it would not do much but it would be somewhat a problem at first.
I also think that it would effect the Bitcoin somehow because many people are selling there coins for the US Dollar so now the users have to search for a other currency and maybe that is going to be harder.
So I am not sure how it would go unless it is going to happen.
