I love the idea but where I come from marihuana Is an illgegal substance. Would it be a problem if I invest into this ICO?
What do you mean by? If marihuana is illegal, would it be illegal to own ATF? IF that's the case then there is no problem at all.
It can only be illegal to own ATF tokens if owning crypto currencies is illegal where you are from. Otherwise what is the subject that the company is dealing with is irrelevant, as long as the business is legal ofcourse. But ATF is planning to sell such appliances only where it is legal, so their business is legal as well.
