According to BlockBeats, on June 17, William Quigley, co-founder of Tether and WAX, said that after the United States approved spot Bitcoin and Ethereum funds, Wall Street's "greed" will drive 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 said that Wall Street's "greed" will drive the growth of such products, and if the Bitcoin ETF is successful, imitators will emerge in an endless stream. He also warned that Wall Street's aggressive marketing of crypto products could pose significant risks, especially during market declines.
