Odaily News William Quigley, co-founder of Tether and WAX, said that after the United States approved Bitcoin and Ethereum spot ETFs, Wall Street's "greed" will bring more and more such products. Quigley predicted that due to Wall Street's relentless pursuit of profits, ETFs for other mainstream cryptocurrencies such as Solana and Cardano will also emerge in large numbers. He added that Wall Street likes the "next hot new thing" because it can talk to consumers and sell their products. But Quigley expects that if the momentum eventually cools down, ETF providers will turn their attention to the next big trend. (Decrypt)
