If I set a 3% loss on my initial investment as a stop loss and a 10% profit as a stop for selling, will that make me trade too often ?
I think you will often make buy and sell orders in a short period of time. 3% down and 10% up will be easy to hit especially if bitcoin is your main currency. You must be very active in monitoring price movements in the hope that you will not miss even a small chance of the fluctuations. Btw, that is a nice idea regardless the percentages you put for both sides.
