Staking option sounds cool if you are going be away from the game for a while and want earn some passive Revv or are a long term holder hoping to sell at a higher ROI months or years later items to collectors.
Or you have a bunch of cars/nfts that you don't use for racing. :) In my case that one epic car can't be driven cause I don't have a driver from MCL34, so it will go into the staking without any doubt. And yes, mining and holding for higher ROI is definitely a lucrative option.
