To prevent yourself from over trading set a ratio between USD and BITCOIN and then make trades to maintain that ratio. You can adjust the ratio higher or lower when you are bearish/bullish. Using a ratio like this is much safer as it will cause you to buy dips and sell rises therefore taking profits when the price is not rising. Also put a gap between trading days so if you like 7 days between trades then each week you would readjust toward your ratio.
