Please explain it the simplest way.
As a SelfKey tokenholder, you will be able to pay for variety of services this platform will have to offer (citizenship and residency by investment, company incorporation, bank accounts, fintech products, insurance, real estate, precious metals purchase and storage etc.). Through your SelfKey Idedntity Wallet you will be able to "digitally sign documents, request identity checks and document certification from certifiers, such as eNotary services, and authenticate at multiple platforms".
So as long as there is company need such service, they will have to purchase tokens from market, and the value will rise. Nice.
