How profit can be earned through funded casascius coins? Why people despirately give up their digital coins to get high value of casascius? Does it is for trading purpose? Also what is the use of casascius without hologram? Whats that used for?
A lot of people have physical coins just for a keepsake or a token from what I know, which can be filled with Bitcoin if they so see fit. I don't use them and chances are I would never use them, but some people might.
I find it doubtful that anyone really trades using them, so I would write that off as an option for trading Bitcoin or whatever.
The hologram either acts are an address or it is a certificate of authenticity, I can't remember. Might be neither.
