I would suggest you to buy something like 5 bitcoins when the Bitcoin price is 280 USD, and sell 4 of the coins when the price is around 350 USD,
5 X 280 = 1400
4 X 350 = 1400
so you will get 1 btc free of cost.
Nice that is kinda a good idea to do. Now just wait untill that Bitcoin goes to 280 dollars.
Going that down you never know when will happend. Maybe it won't go that down this year and 2016.
