It's still developing smart contract platforms similar to EOS. No one can predict the future.
But IOTA has been delivering and will be a ready to go product soon. Many big corporations are already partnering with it. So I would bet on IOTA as an opportunity similar to Bitcoin/Ethereum in its early days. Though these are my 2 cents. Be wise to do some research on each project you think would be viable enough for investing your hard earned money. Cheers!!!
