But how do you buy bitcoins? So far i haven't found a single website that actually worked for me.
The easier ways to get bitcoins are to sell something on bitmit or something like that. Or, you could try localbitcoins and try to buy from someone in your city.
In the US it's fairly easy..
Or post to your local craigslist and ask to pay cash for bitcoins. If you are in a big city, anywhere in the world, chances are you will find a Bitcoin seller.
