The evidence supports the statement. A 2017 article explicitly mentions Mark Cuban comparing the IPO market to the ICO (Initial Coin Offering) mania. He noted that IPOs were at least for publicly traded companies with a measure of liquidity, contrasting them with ICOs. While the evidence uses the term 'ICO' rather than 'meme coin trading,' ICOs were the speculative predecessors, and this comparison represents him questioning the state of the crypto market in relation to the traditional IPO market.
