I made the mistake of moving up way too fast. Got frustrated losing at low stakes to ridiculous hands. Did ok for a while at higher stakes but then started making multiple bad decisions. My bankroll took a big hit and I’m back down at low stakes. It’s a learning curve.If you are asking, if mid stakes games are easier to beat than low stakes games, then the answer is clearly no. Everything else being equal, games get more difficult to beat, the higher you move up. There is an old saying, which goes "maybe I should move up, where they respect my raises". But this is flawed thinking, because if you cant beat the worst players in the game at lower stakes, then there is no chance, you will be able to beat better players at a higher stake. The only exception to this would be, if the lower stakes are excessively raked to the point, where they become unbeatable, but thats more an issue in live poker than it is online.

I think you can still objectively argue higher stakes is more profitable due to lower variance.
As you move up, you will see a lower and lower winrate measured in BB/100 (cash) or ROI (tournaments), but until a certain point this is compensated by the fact, you are playing for more money, and therefore your hourly winrate goes up. At some point though your winrate in BB/100 or ROI drop so fast, that your hourly winrate also drops and eventually become negative. The tricky point is, that we never know for sure, where that point is, so trying to move up is a constant trial-and-error process.
Moreover while its true, that loose games have higher variance in the mathematical sense, downswings will still be much larger and last for longer at higher stakes because of the lower winrate in BB/100 or ROI. You can find high stakes MTT players on PokerStars, who are clearly long term winners, but who lost for 10 years after some initial success. This will not happen in the micros, since games run all the time, and there is always another donkey waiting around the corner to dust off his stack to you.
