How it would be when we have a physical bitcoin currency note? Do they already exist? If created, will it impact the market growth and loose it's value in the market? Any thoughts?
What you are asking for is not going to be possible and I also dont think anyone needs that. Having a paper note or coins for cryptocurrency is not going to work because it is open and not being controlled by anyone. Its just an electronic /digital money and you can only spend it online or offline stores where Bitcoin and any other cryptocurrency you own is being accepted.
