Basically most ICOs. Almost anything that mentions tokenomics. Most of these only function when you have an influx of new buyers. This basically includes all that provide a token to use some smart contract. In the worst case, you have a useless token that you can use with a smart contract that does precisely nothing. Apart from having made some people money and providing money for the affiliated companies, even if they have a business model, it would in most cases be better served to function without blockchain. As someone else said, the most compelling use case is independence from banks and other institutions, which is an ideological position that does not serve most business models.
