That seems like a interesting idea, im glad that we can already see not only BTC physical coins, but also steem ones :D
Well, I might even say that making physical SBD or Steem will be more useful, because you can just use it for visualization. After all, Steemit will become really strong and helpful if it will be extraordinary popular!
I really wish to see our community get larger than other social media, but the Facebook supremacy is just enormous :( No rewards in there haha!
