I may be wrong or right but I still don't see reasons why traders would decides to waste there valuable funds to trade the FUTURE MARKET and still lost there profits and their entire capital when the spot market can be a good alternative to gather good profits but in a slow and steady race.
Why will you choose a high reward trading when your risk to reward ratio could be 50:50?
Its all about money management. Futures trading with leverage, even 100x, may be safer in hands of experience trader than 1x on spot in hands of newbie.
Risk/reward ratio does not depends on leverage you use. Its being set by calculating entry price, stop-loss, take-profit and probability of hitting targets. Not by leverage you used for this trade.
Leverage is only a tool. Its up to you how you will use it.
