Ok, so congratulations! You've got a node--- now what?<p>How do you recover the cost of running your node? Processing rewards/gas are handed out *randomly* so that doesn't sound very enticing. Maybe MEV arbitrage bot?<p>With so many people running "arbitrage bots" and vying for the same pot of gold, is it really that profitable? If it's easy and profitable, this really is a proverbial "perpetual money making machine" and the universal laws of financial entropy suggest it won't remain this way for very long.
