There are two use cases at the moment that I can think off:

1. Proving origin and authenticity of a product through the supply chain (car parts, branded bags, wine). In China for example wine companies lose billions because of counterfeit wines.

2. Alternative currency for unstable countries - like Venezuela where everyone lost confidence in Bolivars due to massive inflation.

Current valuations are hugely inflated and doens't make sense. However, most people are there to earn a quick buck. They don't care about working products. There are many coins that do nothing and are outright scams but are worth billions just because everyone is willing to speculate.

I also feel a lot of people came from Forex trading where trading with leverage is normal. With the volatility of crypto's, leverage is not necessary anymore so that you can't get margin called.

How exactly is that supposed to work. For example I checked http://www.blockverify.io/ and it looks like it relies more on impossible to copy tag than on blockchain.
