If selfkey can really handle transactions without KYC then I am sure it will be a successful project. Currently, there are many people wishing to transact without KYC.
they are afraid of providing KYC and their personal information and are afraid of being sold to terrorists. That is why the demand is very large.
Upon trying out their wallet, they still require KYC but the upside on this is you won't need to fill up KYC requirements over and over again of you'd like to apply for different financial services from their marketplace. Besides that, your data will be saved locally to your device so your data would be safe incase of data breaches on their servers. It's pretty cool actually. The problem is massive adoption for this kind of concept might be hard because most people find the current system as just 'okay'.
