I would like to know specifically who can take part in the project? What countries are allowed access here?
All countries in which there is no ban on activities with cryptocurrencies are likely to be allowed to use the project. It usually happens that way.
About what ban activities are you talking about? I already asked a list of accepted countries but still dont recieve answer. I think it means that all countries are accepted.
As far as I know, some restrictions are imposed precisely by the governments of the countries themselves for their citizens. Like, for example, a ban on participation in ICO for residents of the United States or restrictions on the purchase of cryptocurrency for Chinese citizens.
Although it is not very good decision to prohibit your people to use ICO and cryptocurrency, because it will quickly progress to the market
