ICO financing has been suspended in order to restrict the illegal financing activities through virtual currency, which is threatening the Central Bank's authority and power in issuing currency. Virtual currency does not have the sovereignty legitimacy, government authority, market credibility, and currency reserves as legal tenders supported by the Central Bank’s physical asset and authority. The issuance, liquidity, and transaction of virtual currency are outside of the boundary of legal tender, which cannot be tolerated by the Central Bank and by the government.
