I think buying and holding is not the only investment. Now I find that we can earn bitcoin in many ways like mining mine or participating in signature campaigns. From there we can cum bitcoin and make a profit. Buying and keeping bitcoin is a safe and long-term investment in the future but it is not the only way.
I agree with your point. But, in my opinion, this is the only good way for new entrants to invest in this market. When they do not have much experience, they can follow the waves of the market for more experience.
