Would it be available in Africa?

I think it will be available everywhere, as it is international project

Yes, but this project require a lot of eforts to be implemented in each particular country

I mean countries, where blockchain and cryprocurrencies are not forbidden

This system deployment require connection of hundreds of local organisations, such as banks, insurance agencies in 1 place

Thanks for refinement, now it is clear for me. Is private sale over?

Pre-sale stage is on you can buy tokens
