I am new to bitcoins
I got a new idea in short selling bitcoins
That is , imagine the price of 1 BTC = $1000
I will buy 0.5 BTC for $500
Now I will wait till the price increased by 10% that is , $1100
Now my portfolio becomes $550
Now I will sell the 0.5 BTC for $550 . I got 10 % , $50 profit
Now I will wait till the price again goes below 10% , that is $1000 .
Now I will buy when price again reached to $1000 for the $550 , that is for the total gain.
then the above cycle continues ...
Suppose if the buy price never reach, that is price starts to grow then I will buy for day's or week's low.. and continue the cycle
Is there any exchange that support this automatic job flow ?
