Games Ideas on making a game with a crypto trading economy profitable for players

I've built a multiplayer RTS game similar to starcraft called nBase, and it's available on Google Play. It also has a virtual economy where players can trade/invest in rare items and sell them for CryptoGold (a cryptocurrency I made for the game).

I want to bring the excitement of seeing your inventory go up and making profit to an RTS game.

I'd like it to be similar to trading in CS:GO or TF2 where players can work their way to the top if they are smart and good at negotiating. What kind of creative mechanics would you suggest I add to enable players to make profit?

Also, for any fans of RTS games who want a strategy game on mobile that doesn't require you to wait days/hours to build stuff, what do you think about the gameplay?
