Hey! So, I always max out my fortune and then save up for autosell, speed, and trench. I usually go for the other upgrades after I do all of that as they aren't as important.
And since they're cheap, I occasionally upgrade my haste and efficiency, but not all the way because I only do enough to be able to fly and mine. (eff 15-20 + haste 5-10)
I only just recently started the new olympus season, so I'm not sure if there's another meta I should try, but this works for me <3
