I want to relay to
I am even wondering if this is even legal to begin with, no entity has the right to forbid anyone even if it’s their employees what to invest and what not to invest in. If the Banks have made their policy clear they can’t force its worriers on what to do.
and
I don't think they can actually forbid employees from owning bitcoins considering it's not even illegal there. I'm not familiar with their labor codes though but it would be ridiculous if they can fire employees over this.
Also, isn't Sweden also in the process of developing their own cryptocurrency? Guess this might have something to do with that.
The thing is that the basis behind some investing activities ban is not law
per se but a company code of conduct. It may be considered unethical to engage in certain activities for employees of a company, even if they are perfectly legal. The forbidden activities may involve publicly promoting certain attitudes, activities being on the borderline of legal and illegal (like buying gifts for the company representatives you cooperate with) or
certain investing activities.
I have seen such codes of conduct very frequently. Many friends of mine cannot engage in investing activities without having an explicit OK from the company for each investing case.
I think this is also the case here, in the story from this article.
