What will happen with the €/USD? It's just a curency 'war', we'll see who's printing money faster than the other and how ratings will influence the whole 'war'. My guess would be the € will bounce back at 1.20 for some reason as he always did.
Will this have an effect on the
BTC-price? Nope. The fiat 'price' (or better ratio) is always the same, USD, €, CNY etc. - it does not matter. Guess there are some arbitrage-bots running.
