Excellent presentation friend and i also like to add my opinion why steem is awesome, No.1- steem trx are lightning fast because it took only 3sec to get confirmed, steem mining won't consume huge amount of electricity as it is mined with proof of brain and stake, if for x reason our keys got stolen then steem give us option to recover those keys and one of the best reason why i say steem is awesome because it has zero scalability problem at current load it only consume 0.40% out of 100% and that's huge plus point steem blockchain has over the rest, thanks for sharing such nice presentations with us friend, Stay blessed
