You can buy government bonds now. National debt is a creditor-debtor relationship formed by the state on the basis of its credit and by raising funds from the society. As a kind of government bonds, national debt is issued by the central government to raise financial funds and is the safest investment tool. Because the issuer of national debt is the country, it has the highest credit and is recognized as a safer investment choice. Investment in treasury bonds can earn a fixed interest income, and the principal will be repaid as agreed.
