We are talking the future about the real shape of bitcoin. for now, the concept of bitcoin is the currency in the shape of digits and whether in the future bitcoin will have any real shape like coin or paper?
Based on the description, bitcoin is virtual currency which that is decentralized, Virtual is meaning without any shape, so will be possible if bitcoin be have real shape? The answer is no, because if bitcoin have the real shape, that name isn't bitcoin anymore because isn't same with the description.
If one day there is a new coin but have real shape, will be impossible to use it in the world because the exchange value is to hard to counting, that like price of one coin A is $10 and we want to buy a goods with the price $5 how we can get $5 for the change? with real money? ohh that really hard to use it. Or if the price of one coin A is 0.01$ how many coin we should bring to get a goods around $10? I never thinking about that.
