It's fast! Expected to support 10K transactions per second on 1 CPU-core.
It scales: Their Virtual Machine can do all the calculations in parallel. So easy to add 50 or a 100 cores. According to Dan hundreds of thousands of transactions per second per chain.
It's free: You can't compete with freemium. Look at a company like TomTom with their navigation system. How can they ever compete with Google Maps which is free?? In EOS the dApp creator stakes a bunch
of EOS (they might ask you to help here a bit with some staking) so the Block Producers give them a certain capacity (like 1000 transactions per second). So as a user you don't pay anything. That way someone could make an exchange (like a Poloniex or BitTrex) with zero fees. And by the way: that exchange is in a smart contract no risk that they steal your coins because they can't (if the contract is proper that is ).
