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.
Although this is not a thread to talk about trading, I would like to break some misconceptions about trading in the context of your words. Of course, trading is very risky and a new Bitcoiner should not enter the trade. However, in your statement, you are also referring to the problem trader who is experienced in Bitcoin and also experienced in trading. I would like to leave trading to the choice of a person, especially if he is experienced in this matter. A trader never chooses the profession of trading to get rich quickly if he is skilled. Because he knows that there is a possibility of losing from trading and there is a possibility of profit. You have to take profit from trading by combining profit and loss. It is better for a newbie to view trading negatively and I do not think it is appropriate to advise someone to enter the trade against their will. If someone expresses interest, the first thing a consultant should do is to inform him about the risks.
