Investment and trading is not the same thing. OP actually talks about an investment which usually requires years before it finally turns into a good profit. I think those "newbie cryptocurrency investors" are not prepared to hold, or in other words, they don't want to invest but look for quick and short-term gains, which is more suitable with trading.

That's the basic rule, don't put emotions into investment and only invest the amount that you can afford to lose. If those two are not fulfilled then you won't be able to make a good investment.
