Users can invest in IDO investment products using ETH or USDT. In this case, users’ investment could be collateralized in ETH, USDT, HSF, or the projects’ token. At the end of the investment, users can choose to receive the profit in either project tokens or HSF. If users choose project tokens, users can purchase the tokens at a lower price similar to the IDO platform; if users choose HSF, users will get an extra 5% of the investment returns in HSF.
