Newbies should be even more conservative than that, since their level of skill is so low they should start their journey from the very beginning and that means becoming long term holders at first, as this is the activity that entails the least risk on this market, eventually they could implement strategies like DCA and buying the dip, and only once they have mastered those skills then they can think about the spot markets, and if they did all of that and were successful then they could think about the possibility of trading futures.
In my opinion, it's best for OP or us, if possible, to stay away from futures trading altogether, don't even try it even if we are experienced people in the market. Because even if you are a holder or spot trader but have never participated in futures trading, you do not have any experience with it. The risks are still huge for anyone participating in futures trading, whether newbies or old in the market.
Futures trading is no different from gambling, it is no longer a form of investment like holding and spot trading, so it is best to limit participation in them. Honestly, I've never seen anyone get rich from futures trading, have you seen anyone?
And I agree, however if people are going to try anyway then they need to follow the proper procedure, newbies try to run before they even know how to walk and it is obvious they are going to suffer huge losses if they try to become futures traders, so they need to start slow and gain experience for years before they can even make an attempt to become futures traders, and by the time they gain the necessary experience they will realize how mistaken they were about it and simply avoid it when the time comes.
