the things you mentioned are true often happen nowadays...
with more and more famous name bitcoin, automatically encourage people to try to buy bitcoin with their minimal experience. they don't want to learn first the history of bitcoin, and also the history of its price, all that comes to their mind is profit and get rich overnight. I always remind new people that buying bitcoin is easy, but understanding it and believing in it takes time.
You just need to understand the market in general to trade where you may still be able to hope to make a profit just by buying low and selling high. But in reality crypto trading is not as easy as we think where many factors influence us to get maximum results in the end.
I wouldn't encourage new people to trade, but rather encourage them to invest where the risk they take will be worth the gain. Especially if they are interested in bitcoin then they will be safe to expect profits in the long run without being overly concerned about price volatility. So if they can focus on the initial goal then maximum profit can still expect rather than wanting to make a quick profit by day trading.
