if i could earn enough maybe yes.
We will not earn enough to support living by doing bitcoin only. The bitcoin industry is too small at the moment.
Maybe in 10 years.I hope you are wrong. Firstly, some people are already making a big profit with Bitcoin and, secondly, why "in 10 years"

The speed with which everything changes in the world nowadays is much bigger.
But not all people can make a big profit with bitcoin that's why anyone can't said to others to do a full time on bitcoin and left their real life job even with price kick.
Just to make sure, Im doing both. I trust bitcoin and I can see the price kick in the future.
