I think that preferring the Steem would be the logical choice, in two years the Ferrari's price will have depreciated, Steem on the other hand, while it could go bust, will probably be worth more than it is now, in the meantime with that kind of Steem and just by curating supposing you have a 50/50 payout setup, you should have a nice steady income and this just by up voting posts you like, or you could probably use a bot (something I don't like). But anyway short of Steem disappearing the Steem option beats the Ferrari, money wise.
