Great video, thanks. Indeed, what you often see in the blockchain space is that platforms tend to do better.
One example is Ethereum, which arguably successfully has generalized the smart contract features of many previous blockchains.
Another bet is the decentralized storage space, with companies like Sia, StorJ, Swarm, etc. Today we see Amazon S3-like products emerging, but tomorrow decentralized Dropboxes and YouTubes will be good apps for those platforms.
