Investor and trader are different things. The average wannabe person wants to be a trader, they want to buy some obscure coin in order to get rich quick and they want their invested coin to do x10 quickly so they can move to the next one and make another x10 and so forth. Investor is the person who invests into something so they can make money later on.
For example banks have a lot of money in their "vaults" (not like they keep cash that much anymore) and they put all that money into investments and buy big parts of companies on the stock market so they can actually make profit with money. Money itself is worthless and becomes less valuable overtime so they invest that money into stuff that would later on make more money and worth more. That's what investment is and no crypto investor is like that.
That is precisely the problem, if more people wanted to be investors and put their money in good coins for the long term then they will have nothing to fear from the movements of the market, but many want to buy a coin no one has ever heard and make a huge amount of money in a matter of days and weeks, and as you may guess most of those people are disappointed with the market.
