HHmm how do you tax a transaction made in ebaycoin over a multinational distributed ebay ledger.
It could be as simple as an internal mechanism for transferring large sums of small transactions at zero cost while tagging each transaction with a loyalty number linked to individual users.
ofcourse i'm probably completely wrong and should probably shut up now.
With paying tax is simple you pay your own and declare your own if you are within budget for the year and not over it, depending on where you live don't have to worry about it so long as it is within the budgeted amount each year and if over then have to submit to pay tax on but many do not even bother to and risk tax dodging.
