i using my earnings from yobit signature campaign then i will trade it for profit. as now i gained 0.005 in yobit campaign and i will roll it for trading purpose.
this is a good thing that you are doing because this way you are learning how to trade while risking very small amount.
but i suggest you trade on another exchanger because on yobit, except 5 coins others are dead and nobody even trades them.
as i see these few days of observing in trading strategy is to predict whether it will increase or decrease using their chart at the top of the buy and sell option, if you predict wrong you will lose bitcoins or you will earn very small profit.
you should make sure to buy at the bottom (buy low) and sell after the rise, not exactly on top but only selling higher in a profit that you are comfortable with.
