in 10 years i may be able to completely rely on steem but not now. for me to be able to survive on steem i would need about 300k steem power at current prices. or the prices wil have to jump really high before we even consider doing that.
the delegation should be able to provide about $3000 worth tokens each month before we call it serious income. right now we get pennies but alot can happen in 10 years.
