Most alts are nothing more than promises - invest in tokens like temtum that didn't do and ico OR ieo , privately funded and now working with Anguilla to deploy their national currency.
https://chbt.ch/ has done all that only they have working, real world, products that are in use by the legal, medical, and insurance industries. And that is just the beginning. These guys are servicing entire worldwide industries, not just one tiny country.
You have not heard of them because, like true professionals, they got their product working and rolled out properly before inviting people to check it out.
They have done all this? As far as I am aware they don't have an LOI for a national currency like TemTum...
