A thought occured to me just now. In the future, when the block reward is miniscule and the Bitcoin network's miner's revenue comes solely from transaction fees, wouldn't large bag holders have an incentive to mine blocks just to keep their bags secure regardless of whether the transaction fees make it profitable or not? I feel like if Bitcoin is worth enough money then anyone with a significant amount would at least have an incentive to protect their wealth by mining. Am I wrong? I would love to hear what other people think. #bitcoin
