I would say $30, still its 1000% growth from $3. At $30 STEEM will have market cap of $7.5, 10% of ETH's market cap. STEEM to be there, SMT should be a huge success story similar to ETH's ERC20.
However, even if we reach $100. I would split $100 a STEEM as People/Market understand that STEEM is faster, scalable, secure and has more utility (savings, powerup, delegation) than BTC and LTC: $10-20 a STEEM. Some of the bigger exchanges adopt STEEM (e.g. Bitfinance, Bithumb, Binance etc. and Coinbase can bring STEEM to $100) $20-40 a STEEM. Steem blockchain has 5-10M users (i.e. users can grow exponentially if signup process get easier and network effect takes place) $40-60 a STEEM. SMT brought some of the biggest names from Media (i.e. Media companies, specially news outlets are starving for profit model and blockchain adoption quadruples company's stock ) and lots of SMT based ICO get success and compete with ETH as well as Wall Street money chip in: STEEM $60-100!
