So I was wondering about this scenario: Lets assume market cap goes up a lot, lets just say to 1 billion. Suddenly everything crashes hard, like crypto has no more value for whatever reason (just a scenario) and nobody wants to buy crypto anymore, but radix can only loose so much value as the system can burn (a lot of might belocked in the wallets). But since 1radix = 1usd I just can sell my radix? The "system" just buys up my radix with usd? Where does the usd come from (assume no "real" buyers)?
