Given that blockchain related jobs are among the fastest growing in today’s labor market, it is safe to assume that the demand for blockchain experts are also growing at a significant rate. The average income of a Blockchain developer (in US) have also increased by roughly 50% compared to that of the average software developer.
There are now many job openings for every one Blockchain developer. I am very sure that these statistics are already enough to give you assurance about the future of the industry and job market.
But just in case you do need more data, here’s another. Nick Szabo (who is suspected of being Satoshi Nakamoto the founder of bitcoin) rightly points out the “extreme $/knowledge” ratio in the Blockchain sector, where capital by far outpaces talent hence signifying a demand in this field.
