Bitcoin is a very fast booming and rising currency and I have been hearing about there being a physical bitcoin I mean in the form of a metal. Now if this is possible I would like to know if bitcoin would be a generally accepted means of payment in the next years to come and what are the possibilities of other currencies meeting it( I mean in demand and supply)
I too heard about these physical bitcoin which are called casascius coins which has a bitcoin valvue depending on the material and its balance. Casascius coins has a paper like thingy inside it which has a private key embedded into it that has Bitcoins inside once redeemed. So yeah, it's like a paper wallet and nothing more.
