Margie Feng is marketing lead at Solayer, the Solana-compatible layer-one and the team behind Margin Trade, a non-custodial perpetuals platform that lets traders hold crypto, commodities and equities in a single cross-margin account. Feng came to Web3 from Bitmain, the world's largest crypto-mining hardware maker, and before that ran PR and marketing in the automotive industry for luxury marques including BMW and Genesis, an unusual path that informs her core pitch: she markets as the non-technical user she is, translating complicated machinery into something an ordinary trader actually wants.
