Ok . I will start buying some bitcoins or other alt-coins but which is the safest and most profitable place where I could buy ? I saw that mxgot has disappeared. I will look into the trading part of the coins .
Depends on several factors and where you live etc. just use cryptsy or btc-e. you can use bittylicious if you're in the uk.
Agreed, go to BTC-e for volumes and Cryptsy for niche coins.
