I had no plans to pay $140 to get myself certified - that didn't seem like much use to me. Of course some of us would be interested - but I think it's just a collection instead a condition for applying for a job. Certificates can be useful - but not all jobs require certificates especially if they only want your experience and ability on the job.

A certificate might explain to your future children that you are one of the many people who know and are knowledgeable about bitcoin - but I don't think it's very useful for the company that will hire you.
