Do you know the difference between cryptocurrencies and stocks.Cryptocurrencies aren't designed to payout dividends.Therefore you are not distinguishing trading from investing.Some people invest in stocks,while other people are trading stocks.The stock traders aren't waiting for dividends,they buying low and selling high.
The term "investment product" is really disturbing here.
I don't want to comment all the mistakes in that Youtube video.OP,just read more books about economy and finance and go to a university,if you are interested in that subject.
