I voted FOR this proposal as I generally agree with the plan of responsibly managing the DAO’s funds and making sure there is enough runway for 2 years.The team has expenses and we need to make sure they are covered even if it the market takes another downturn.
As for using cowswap instead of a gnosis auction as @middleway.eth suggested, that’s an interesting idea. Has any such big swap happened via cowswap? The commands look straightforward.
Regarding the question of splitting up into smaller sells, that may indeed be a good idea, but depends on how far apart they would be executed. As you may avoid slippage but as mentioned above you are exposed to ETH’s own volatility.
