This is an obvious act of IDIOCY 
Why would your employer do such an irrational thing? 
It is a joke when I first heard it. Because if you will retire, there are a lot of tendencies to happen. Like: what if bitcoin that time already died? It is not impossible because there are a lot of new coins on the market nowadays. Also if that happens, how could you support yourself if your salary will go to that wallet? This is funny thing you know.

This is a great risk both for the organization or the employer who is going on to pay the pension for the person and for the retired guy as well.
