...If I can gain good skills in spot trading, then I can decide to do futures trading later. If I decide, I will definitely use 1% to maximum 5% leverage. I will never use more leverage because I never want to put my money at risk or at maximum risk.
Spot trading and futures trading are entirely different games and you must be grounded in the game before you attempt futures trading else you will get burnt so badly. Before you attempt futures trading, you must do your homework well about the asset you want to trade if it is one with low liquidity because such asset often fail technical analysis. However, if it is a high liquidity asset like Bitcoin, then it does obey technical analysis a lot but you should still check fundamentals. Therefore, work on getting a working strategy that you have tested and confirmed before going live on futures trading.
