And my Miners are officially not profitable anymore

-21 cents per day on 4 machines. Let see what the next weeks bring, maybe I turn them off if the price drops further or diff keeps climbing like that.
And yes, I also believe we should face that L4 is real and hashing. I fully believe humanity is stupid in general, but I doubt we find that many idiots buying L3++ in the last couple of weeks, that we can rule out the existence of L4 and blame diff increase on them...
