Assuming Steem (current $1.1b) reached current market cap of Bitcoin ~$236b that would be ~$1,180 a coin assuming coins in circulation remained the same. Still not $1500 but not too outrageous if you project Steem to be the #1 coin in the future. I think trillions of dollars will flow into crypto markets before any big bust occurs. I think Steem around ~$1000 is not completely unattainable in 5-10 years provided the Steemit community keeps taking the right steps.
