I dont mine bitcoins. I only do services in exchange of btc 

I reallny don't see it dying anytime soon. Too much money are into Bitcoin atm.

In my country? Pretty much non-existent. Haha

That would be great but it's a bit risky in my opinion

Basically do your own research

Yes. It it being used for illegal activities; but, so is real physical currencies.

Why the need to? Just explain what you can do with bitcoins. You dont need to explain blockchain, etc
