If a whole digital currency doesnt work out in this digital era, what makes you think that the physical coin is going to be the one that will be accepted by the people.? Nah thats not going to work. I will even be among those that will be against this coin thing. First you should try to imagine how possible it is for people to make use of this thing you have here. How exactly are they going to make use of this physical coin?? By selling it? Does that make any sense? For me I dont really think so. And if the government gets you with this, you might even have a big problem with them.
