Here's what I did recently. I took all my bitcoins and put it into an exchange. I then used that to buy litecoins yesterday. I slept.
The next day, I made a sell order for twice the price. I got it, and almost doubled my bitcoins. (I forgot about the trade fees, etc.)
I now just need to withdraw my coins from the exchange, but it won't let me because my account is only 2 days old.
My holdings are very small, so in terms of USD, I just made a thousand dollars today. (I only had 1 bitcoin, it's now 1.999.)
I'd classify you to the "lucky" ones. I will explain this sortly: If you repeat the process, let's say every day from now on (only your profits - not the 1BTC you started with), what's your possibility of doubling again?
Hint: I'd stash these 2BTCs away for about 2-3years from now and be glad about it.
