I appreciate what you said but you said bitcoin accepted everywhere but i saw most of the countries not support bitcoin and not even any other crypto currencies and its seems in most countries in Asia. You most exciting reasons to become involved with digital currencies and you said about exchanging coin to USD but my friend there are so many sites which are not legit and some sites which charge a lot of exchanging. I found a directory where all crypto currency related solution and i can exchange Crypto currencies them in lower exchange fee.
