SUI Token and Market Context

SUI is the native token of Sui, a Layer-1 blockchain that launched its mainnet on May 3 after a lengthy development period. With a total supply of 10 billion tokens, Sui has a diluted market cap of 12.8 billion USD. However, its current market cap is only 650 million USD, given the circulating supply of approximately 500 million tokens.
The SUI token release has also faced controversy, as the token was sold on exchanges rather than being airdropped to early testnet participants.
