I know there should be big difference between various countries.
A developer with two years of experience in China may earn 15,000 a month(21.75 days), or 86 RMB (~12.5 USD) an hour (8 hours a day).
The best blockchain developers can't be bought -- and certainly not by the hour.

Direct to the point mate and i would say the same thing too.They wont bother to work for someone but they will work for their own project that could able to make them millions of dollars.
