This is the biggest problem I can see right now. Treasury companies with no proof of reserve. Of the top 20 companies only Meta Plannet and XXI are doing it. Anyone without it is suspect. Would you take someones "attestation" that they had the money instead of just a pubkey... No.. Anyone who thinks this is ok is clearly cheating. "oh its ok, I don't need easy cirtainty, i'll take your word for it regarding the thousands of bitcoin"
