I'm not clear on this one point. If somebody got a hold of my private key and moved funds from an address that I claimed on the ledger, is that against the law? At what point could that be considered a crime? For example, if they hacked into my machine and stolen the private key; if they sniped the pk while snooping on a public access connection; brute forced the pk into existence; or just plane snapped a shot of my qr code over my shoulder....ect In which of those examples could I pursue prosecution for the theft of my coin?
Yes ofcourse its illegal and any person whom you don't allow access to your money takes access in any unethical manner would be illegal. But problem is which country's law is going to give you shelter in such a crime. I dont know any country which pertains any law regarding bitcoin theft. Moreover private key doesn't has any owners name affixed with it. So it will be a heck of problem for you to claim that these btc were actually yours.
the state will not be willing to assist you because no rules apply, all ownership is your responsibility, very ironic, but if individual theft cases apply, there will be no valid evidence in the process of case recapitulation that requires at least two evidences. unless you follow a HYIP crypto that is currently running in your country and result in a loss, then the owner can be processed with a fraud case.
