yes, in my opinion that's the worst idea, if employees in the company / office trade Altcoin at work / office, what else in this government is very bad to do it.

A professional does not involve office work with personal work.

I do trading at home never bring individual problems to the office, employees should serve the people who need it, instead we have to do our work in public places, we are paid by the government to serve the community.
Not vice versa, individuals do personal activities in the office that can harm many people, because the individual is not professional in sharing work time.
