On January 20, Vitalik Buterin, co-founder of Ethereum, posted on social media about the suggestion that the Ethereum Foundation could pledge its ETH, saying that the historical concerns are: 1. Regulatory issues; 2. If the Ethereum Foundation pledges itself, this effectively forces us to take a position on any future controversial hard forks. Regulatory issues are less than before, but there are still problems with the Ethereum Foundation pledging itself. There are definitely ways to minimize, and we've been exploring those recently.
