Arthur Hayes, co-founder of BitMEX, expressed strong support for altcoins during his appearance at Consensus 2026 in Miami. Hayes argued that while 99% of altcoins, often referred to as 'shitcoins', may eventually become worthless, this is not unlike the historical performance of the S&P 500, where 98% of companies have disappeared since 1929. His comments highlight a belief in the enduring potential of altcoins despite their volatility and high failure rate.
