Why???
We've decided to ban Ukraine due to the unstable bitcoin environment that we feel in there, not only because the country is being banned. we are aiming to protect our global investors and eliminate the risk as much as we possibly could. We sincerely know it will cause much inconvenience, but we have to do this to make sure the project running smoothly.
Best regards,
ArcBlock Team
I think the reason ArcBlock does not allow investors from Ukraine is that: your community likes to trade = sell tokens right after ICO to gain profit from difference, which affects the token's liquidity; or your government has issued a code prohibiting crypto / ICO.
