ctUSD risks

Fiat-backed issuers can usually freeze tokens at specific addresses, for example to comply with sanctions or court orders.
With $3.6M in circulation, exiting a large position may move the price. Redemption may be limited to approved customers.
Rules such as the US GENIUS Act and the EU's MiCA can restrict which stablecoins exchanges list in a given country.
