It seems that the project was made available to banks a long time ago. However, since politics was involved in the project, I think most users were afraid to participate, personally I was worried.
The web connection of the project currently does not contain an SSL certificate, that is, it is not secure, and I think that the information shared in it is both incomplete and not very plain, that is, it is written in official language. In addition, this project used to have too many followers in the Twitter account, but now this account is suspended, as you know, accounts that do not comply with the use of Twitter are suspended. Maybe it was suspended for a different reason, so I'm not sure.
The BERN token is currently being exchanged for the BTC currency on the yobit exchange, which is known by many users. Since it is listed on only one exchange, it has very little value, I think it will be completely worthless when the transaction is canceled in this exchange. Also, for a long time, this token has no transaction volume, so there has been no user of the token for a long time. When I looked at the charts of the token, I saw that a time value had risen too high and suddenly decreased, and in this case many users may have lost money.
In general, I do not see any benefit in this project anymore and I suggest you stay away.
