Trading with bitcoin is a very big mistake for anybody, not just newbies, it shows lack of patience, but beyond that, it also shows complete lack of understanding of how bitcoin works, its not a get-rich quick scheme, it's also not some kind of a magic trick where you wave a wand and the price jumps up on your order, it takes time and should never be used as a source of getting quick cash, this has made many people bankrupt and is still doing so to people who are refusing to understand that bitcoin market it for investing not trading, if a person is deciding to trade with shitcoins, that is their business as is the losses the will accumulate in the process, but never go into bitcoin with the intention of trading.
If we look at the data between traders and investors who are successful with their respective jobs, of course there is still a higher percentage of traders who fail than investors who are unsuccessful because on average almost all Bitcoin investors always manage to make a profit as long as they can be patient for several years by continuing to run their investments routinely. So we can conclude that trading with anything including Bitcoin is a step that contains a higher level of risk so it is very natural for some people to avoid trading and prefer to just make investments without having to bother their heads to keep looking at price charts in the market for Bitcoin or other coins.
I think it is mostly greed that make some people make the decision of trading Bitcoin rather than investing and holding. They believe that investing is too slow and will not give the kind of fast profits they want hence they need fast way of making the profits and trading is one thing that looks like it holds the answer even though in the end it is not always as easy as it seems. Trading is very risky and something not meant for those who are not ready to lose their money. Investing on the hand, is more reliable in the sense that it gives the assurance of profits when held for a long period of time.
