Yes, making a profit and not missing the future opportunity is the major reason for investment but most crypto investors ignore the technological or fundamental, utility and use case aspect of a project before flocking into a certain coin for profit.
Actually I totally agree with your assumption on this one. Many traders and investors seem to overlook some of the above simply because they are so focused on future returns and don't consider what the function of the asset they are investing in does. I would even venture to say that they don't want to know much about the assets they invest in other than just expecting huge returns as a result of their investment.
I'm not going to argue about that because I think it's a fact. While there is no research on how much people care or not about the use cases of the crypto assets they invest in, I believe many traders and investors ignore it.
