Last few months I saw an article, that make me shocked, how some killer open their mouth in the court to tell the judge how the woman paid them with bitcoin to her husband that is making court to start investigating how the transaction was made to carry out such act. Assume it's fiat money she use to pay the killer, do you think the court will still like to investigate the type of currency used for the operation?
If the judge has no knowledge about Cryptocurrency he can get a resource person, to enlighten him so he can render a good decision, but they do not have to investigate Cryptocurrency on it's entirety, they judge just need to see if there is a crime committed, who commit and why it was committed and render a fair and right decision.
