Thanks DannyHamilton that was comforting. Albeit I had moved my bitcoins to another wallet in panic, the transaction had later been confirmed (of course without sweeping my account!). I just learn as I go on. I use a blockchain wallet by the way and I'm new as the word itself! Now I'm just hoping I really get paid by the site as promised....ever used them? 2xcoins.org
Those BTC "doublers" are called HYIPs and they will scam you sooner or later. Bitcoin is money and it's not that easy to double your money. I suggest you stop using them.
