Op i don't think you have full idea about both trading otherwise you don't ask about which trading is best for new comers. Spot trading is normal trading which offer 1x leverage but future trading offer leverage from 2x to 20x even more in some cases. Spot trading is safe more but future trading has higher risk. As you are newbie, one mistake could empty your entire balance without let you know but with spot trading, you can learn with mistakes and gain better experience
The points you explain are also quite basic and also very appropriate for this topic because basically spot trading and futures trading are very different in terms of risk even though the way they are done is almost the same. So it is better for anyone not to recommend futures trading to beginners if they still need special learning in terms of trading, so that beginners can try spot trading as a place to learn and also as a place for their own actions in gaining experience through the market.
