Ethereum Developer Conference ETHDenver conducts a dining car experiment for cryptocurrency payments

Ethereum Developer Conference ETHDenver conducts a dining car experiment using cryptocurrency DAI payment. Experimental results show that ETHDenver conference participants used DAI to pay for food cart food transactions with 60% success, but 40% of the transactions were unsuccessful. It is reported that many discussions within ETHDenver involve generating revenue through DeFi, but the most basic use of cryptocurrencies (as a payment method) is still being developed.
