There are many ways STEEM can reach $100 mark: People/market understand STEEM is faster, scalable, secure than BTC, LTC even ETH; Bigger exchanges- STEEM is not yet listed in three Big B exchanges (Bitfinex, Binance, Bithumb), but its companion EOS is there; larger-userbase- currently we have 0.6M userbase, we can have 6M in a year with easy signup process; STEEM can rise on speculation due to being target of next most Airdropped target coin (e.g. VICEcoin).
People are talking can STEEM rise to $1000, $2000 or even $3000.
