BnkToTheFuture co-founder and CEO Simon Dixon stated in a Bitcoin Magazine video interview that there are only three scenarios that would make him sell all his Bitcoin and buy gold: if Bitcoin can no longer be held in a self-custodial manner and generate returns, if peer-to-peer payments cannot be completed without a governmental intermediary, and if the fixed supply of 21 million coins is no longer credible. He mentioned that Bitcoin has performed well in these three aspects since 2011, and if any of them are called into question, he would sell immediately.Dixon believes that the real battleground is not whether Bitcoin can be adopted, as the trajectory of institutional adoption is unprecedented, but rather whether custodial institutions, Wall Street-controlled mining companies, and treasury companies will lead the network towards centralization. He pointed out that if everyone hands over their private keys to institutions like BlackRock, Bitcoin will fail.He also discussed the phenomenon of central banks continuously buying gold instead of Bitcoin and emphasized that holding private keys is a form of resistance; investors need to allocate assets outside of the traditional banking system.

According to Bloomberg, the crypto market maker Wintermute has become the main user of Hyperliquid's priority data auction mechanism.
