The thread was made in 2016, but this is important for many people to know. Some countries use the basis of Anglo and civil law, the difference is codified and the logic of thinking of judges. But I think both of them have the same goal, namely the logic of thinking. So, if there is a legal dispute for the owner of bitcoin it will be easy to solve. Because bitcoin technology is a proven mathematical logic, there are many examples of people claiming to be satosi but they are not legally proven to be owners of bitcoin.
Ownership of bitcoin is anonymous so it remains mysterious who is the owner of bitcoin. But based on the ownership code, it is known who the real owner is when interesting in bitcoin exchanges.
There are indeed good and bad sides to this anonymous ownership, but everything that happens in cyberspace is still an unknown thing. Future technology does require clear regulations from each country to prevent negative effects, so criminals are not used.
