This is a good question. I believe that is quite hard for blockchain based projects to achieve the level or standard platforms because of their new age, user interface or technical reasons. I believe that some industries have it easier to perform and reach users if they have a user friendly interface and the concept is simple. Lets take transaction applications or communication platforms. I've been using lately Sylo, which right now is a semi-centralized platform for communication. They have been around for few years, so they are not just another ICO. Since blockchain offers easier decentralization through it's nodes, Sylo team used P2P technology combined with a blockchain protocol to make communication immutable or basically fully decentralized. This is an example, so projects that have a working product and try to use blockchain to improve it, may stand a change. But having other projects that rely on blockchain alone and have just started will be quite hard to get on top in their respective niche.
