Overall I support this proposal, the last few event proposals were very difficult to coordinate though the DAO and having a committee dedicated to it would make more sense.
While I want to cut spending, marketing and coordinating at events is probably worth it.
It is a smart move to keep Arbitrum visible at key industry events. And I actually like the idea of having presence at a BTC event. The oversight from Entropy, ADPC, and Disruption Joe is solid, and I appreciate that unused funds go back to the DAO.
I would prefer that the group hold ARB until it is spent, even if it was allocated 10M ARB, for exchange rate risk, that would be better than selling all the ARB now and then holding stables to see if it is spent.
But I do support this effort and wish it had happened earlier so that maybe we could have had GovHack in Devcon!
