Remember, this whole thing about crypto is largely decentralized, thus, there is no single authoritative body in control of the crypto market. Although there are few centralized platforms among crypto, the market is largely influenced by the efforts and influence of the users of crypto. How well sellers and buyers treat the coins on the market affect the performance of the market.
Which is why most coins that are being introduced into the market are more Millennial friendly. Statistics show that they are the major influencers in the crypto world and so have a certain amount of influence on a coin's performance in the market. Decentralisation eliminates the middlemen, yes; but puts control in the hands of millennials, therefore, new projects for example Tapcoin which is a hospitality/leisure based project and offers discounts to its users on expenses made on drinks and hotel booking through their credit card. More so, Traveler, Dataeum, etc are other Millennial-related projects are more likely to succeed.
