I have been concerned for some time that Etherium is over subscribed, almost every new ICO and token is built on it and this presents huge risk in that there is so much money centralized onto one platform. More so, if critical societal functions like energy networks (guess what, energy is requred for blockchains) all use one platform, then a failure of one underlying system can become extremely damaging.
Id advocate for people doing things the hard way, building custom block-chains which are proofed against these sorts of bugs, or at least having them only effect one of many discrete systems.
