CRYPTO20 is a tokenized crypto index fund. Its token trades listed as C20.
The ethereum based, ERC20 compliant smart contract allows for liquidation process. Holders can redeem tokens for the Ether equivalent of the calculated NAV of the crypto assets held by the fund, less an 1% trading fee.
Marketcap or market-share debate aside, cap-ceiling at 10% may cause clearly distinct behaviour from what would be a no-cap portfolio distribution.
