Is it legal to have a Bitcoin income and not pay taxes on it? Are Bitcoins considered as real money by the governments?

Well, it depends on the hardware you have, especially your GPU.

In your opinion, what's the best BitCoin to PayPal or LibertyReserve exchange out there? It should be instant if possible.

This sounds a bit fishy. I mean, if he doesn't even offer a proper product, and just wants you to send him Bitcoins like that, then he's probably a scammer.

Sounds nice, I will probably check it out soon.

Just search for Bitcoin exchanges with a search engine - they're all International (well, virtually all).

I would say in a group.

Why? Security, reliability, ease of use.

I like all kinds of music, but especially military choirs for some reason.
