What is the most profitable thing to do in Sea of Thieves?

I'm curious, what would you say is the most profitable endeavor one could embark on in the vast and treacherous world of Sea of Thieves? Is it hoarding treasure chests and selling them at Outposts for a hefty profit? Or perhaps engaging in risky but rewarding pirate battles for the spoils of war? Or could it be something entirely different, like mastering the art of fishing or trading goods between islands? I'm eager to hear your thoughts on the most lucrative path to take in this pirate-filled adventure.
