Hey
humm you have good strategy your thinking is great BUT you have to do some math Bro , trading with 20 cents (for me) is hard to make good amount of money it will take you so so much time and energy... so if your goal just to test, learning about trading and bitcoin or have fun & enjoy its ok you can do it.
but if you'r serious about trading you should invest time (for learning) & some money minimum (100$) to start and then grow it slow, by creating a trading plan (strategy Technical Analyst, Risk management...)

Wish you all the best Bro..
