Today I still trade futures only when I see the risk are crazily low then I go in with a substantial amount. But you see those opportunities are rare and difficult to catch except with a well planned limit entry.
Also, you must have studied the market to know the major support and resistance of these token to be able to enter a short or a long trade with confidence.
Therefore, if you have not mastered it be patient, buy Spot and set limit sell around 40 to 50% ROI.
