Show me where I can buy a permanent domain directly from ICANN and be sure that it will be stored forever without ever relying on a single company or system to keep working and I will suggest it over any blockchain solution immediately. The problem is that it does not exist and it probably never will, and thus this is the next big thing.

Also relevant LOL (although you're right when it comes to blockchain and cancer, this is nonsense, I just though it was funny): https://www.independent.co.uk/news/business/business-reporte...
