I would say that most of cryptocurrencies are just means of monetization for various projects. People mainly invest in projects, because they want to earn profits from it. People don't buy clothes or cars for the same reasons, they rather do it to follow fashion. After some time cryptocurrencies might indeed become a subject of fashion, especially if we talk about the projects which are related to healthcare, charity or ecology. For now, however, that is not the case, so my answer to your question is negative.
