Based on my calculations my love cost me ~300k sats in 3 years. Also, what do you call a profit, like raspberry pie is approx 4W of power, which is approx 1 EUR per months where I live. So yes, you can technically have more than 3000 sats per months in fees and .... profit!! ( if let's say you got pie for free and opened your channels at 1 sat vB) so a lot of nuance. I think right now it's a game of liquidity, to have real profit you must open several 0,5 - 1 BTC channels
