sUSD is a stable coin similar to the dollar. It is a project running on ERC20 infrastructure. We can say that 1 sUSD = 1 USD. It has a supply of approximately 22,510,653. Those who are disturbed by the volatility of other unstable cryptocurrencies can invest in such stable coins. My opinion is that it is better to invest in such stable coins rather than dollars. Because our world has now reached very different levels in digital and technology. Maybe there will be no paper money in the near future. Therefore, sUSD and similar stable coins have nice advantages.
