If you want to LEARN all about bitcoin, your money is better spent getting something like Andreas Antonopoulos' book. But if you want to help build up some credibility FOR (not IN) the "crypto industry", then CBP isn't a bad place to start.
"Professional certifications" certainly have a value for HR departments and consultants. 99% of certs are a scam, because the people who certify you are the same people who make/sell the products you're certified on. Which could also be true in this case, except that the Bitcoin tools and docs are free. So why buy a certification?
The people offering this certification might be too early - but it has to start somewhere. The CPB level is like a secretary's (sorry, executive assistant's!) proof of basic competence like ability to type X wpm, understand filing systems and have good phone manners. If a business has to or plans to handle bitcoins in the future, then their HR dept. will be happy to find a candidate that at least knows not to put the private keys unencrypted on a removable thumb drive.
But it's "too early" because no business is asking for it yet. It's bootstrapping - people need to learn about Bitcoins to want them, and who better to spread the word than a CBP? When HR personnel start seeing "CBP" on resumes, they'll get used to and start to demand it - even if they don't know what is it. (Intelligence isn't a requirement for HR work afaik
)
The CBP certification is superficial because the technology is brand new. You don't really need to hire someone to set up a wallet hierarchy for your departments and be a "key master"/wallet admin because the wallets aren't that complicated yet. But someday they will be and then CBP will certainly be "worth" something.
On the other hand, how many current "altcoin devs" would fail to achieve even basic CBP level? I'd love to know!
I think it might end up like the "Scrum Master" cert. About 100$ CAD (when I did it), a couple hours of reading, easy exam, but being able to apply to "Scrum master"/Agile jobs is worth the cost, even if Scrum is a scam. Laugh at the people spending money all you want, there will *always* be cert. programs when $ is involved. This one is probably not worth it for anyone savvy enough to be on bitcointalk, but it only takes one big HR department to start demanding "something" for a certification program to pop up. All the better if it's run by a non-profit, right?
C4/CBP does have some failings, in my opinion. First off there is no publicly visible count of how many people have achieved CBP, or even applied. That doesn't encourage businesses/HR to demand it or vet its worth. There's no official training material or "trial" test. And as far as I know they don't offer to link to a live logo/visible certificate you could put on linkedin or whatever.
So personally I'm going to use my money to buy another 0.5 BTC
But as a professional software dev, I am definitely looking forward to the CBX cert!
