Silicon Valley angel investor Liron Shapira expressed a 50% confidence that Bitcoin's price could drop more than 50% in the next two years, citing AI's rapid development as potentially undermining market confidence in Bitcoin's security and robustness. Ethereum co-founder Vitalik Buterin disagreed, remaining optimistic about long-term network security. He argued that the main challenge is executing the transition, noting that Bitcoin can handle issues not requiring social consensus, such as upgrading clients and mining pools to counter network-layer attacks. Vitalik deemed the probability of a successful attack on hash algorithms or the PoW mechanism extremely low. He revealed that he has bet on this view through asset allocation, with approximately 90% of his net worth now in crypto assets.

BlockBeats said on September 7 that Silicon Valley angel investor Liron Shapira put himself at roughly 50% confidence that Bitcoin will fall by more than 50% in the next two years. His argument is blunt: fast AI progress could chip away at the market’s old view of Bitcoin as secure and tough, and that could put BTC’s long-term value case at risk.

But Ethereum co-founder Vitalik Buterin pushed back. He said he feels positive about cybersecurity over the long run. The real problem, in his view, is making the transition work. Vitalik said Bitcoin is a good fit for dealing with issues that do not need social consensus—for example, upgrading client software and mining pools to protect against network-layer attacks. And he said the odds of a serious break in the hash algorithm or the proof-of-work mechanism are extremely low. One more point. Vitalik said he has backed that view with his own asset allocation, with about 90% of his net worth now invested in crypto assets.
