Jan3 CEO Samson Mow has reignited the debate over cryptocurrency's role by critiquing Ethereum's currency functionality and advocating for Bitcoin as sound money. Mow argues that Bitcoin's adoption patterns, such as companies paying salaries in BTC and the use of the Lightning Network for microtransactions, demonstrate its effectiveness as a currency. In contrast, he points out that the Ethereum Foundation's regular sale of ETH and the lack of salaries paid in ETH within its community undermine Ethereum's store of value and medium of exchange capabilities. Mow's analysis highlights Bitcoin's fixed supply and proof-of-work consensus as key factors supporting its monetary characteristics, while Ethereum's inflationary tokenomics and governance centralization pose challenges. As the cryptocurrency landscape matures with clearer regulations and institutional adoption, Mow's observations underscore the distinct roles Bitcoin and Ethereum may play in the digital economy.
