While those exist, the crypto mechanic will act like a short cut and then you've got pay 2 win still.
You cant shortcut with this design. Your level of your character is tied directly to your profit margin. The more money you spend on the character the lower your profit margin will be thus spending money reduces you characters level. And harder content requires that you you have higher level (profit margin)
Your success is directly tied to how much money you make from the game.
