Bitcoin as a retirement account?

I am 31, and wondering if anyone else around this age has chosen to not put money into a retirement account at work and instead put it into Bitcoin instead? Obviously this isn’t a very traditional or risk-off approach but I believe in this thing and I think it could work. It’s been amazing watching Bitcoin transcend into society over the past year. Or if not retirement, do you do anything against the grain or that is not very common with Bitcoin that you don’t know anyone else does?
