Interesting to see Washington that high. I would have expected somewhere like San Fransisco or even New York (third and fifth respectively) to be at the top but somehow Washington is at the top. There will be more and more companies hiring blockchain developers for sure, think of it as a software development job and not just something new and related to crypto directly. Like for example people do search for C# developers right? They are also looking for phyton developers?
There are tons of other languages like that as well, most software developers know at least 2 or 3 of course but there are newbies who are good at just one. Think of blockchain developers like that, just a software developer who learned Java, than phyton and now blockhain, and applies for that kind of jobs, its gonna get only bigger.
