The age preference put up of 18-24 was to find any overlooked talent out there that isn't getting a fair shake because of their age.
Wow, really? Right now if you're young and have any kind of degree at all, there is no way you can be overlooked. There's more jobs than graduates.
On the other hand, if you're over 40, don't quit your job unless you have a contract somewhere else! People will just assume you're too old to learn new technologies or that they can hire two kids for the price of one veteran.
In France it's a common occurrence for IT/devs to be 'shelved' at 40 apparently.
At least here ageism is still illegal...
Just saying... The best way to succeed is to have both young pups and an experienced bear or two.
(Sorry, this type of stuff makes me mad. Every single want-add for software dev. wants 'young, dynamic' people... As if having to death march to deadlines and staying at work all weekends was somehow an attractive plan. sheesh.
I can see there's something wrong going on and it's only going to get worse, but no one talks about it.)
Anyway, good luck with your project, any Bitcoin development in Canada is great news.
