Court decisions regarding cryptocurrencies play a key role in the evolution of sector regulation. Indeed, when it comes to stolen funds, the issue becomes even more sensitive, as it pits the principle of confiscation against that of restitution to the victims. The case of the Bitfinex hack in 2016, one of the largest Bitcoin thefts in history, crystallizes these tensions. After the seizure of 94,643 BTC by US authorities, the courts are questioning the appropriateness of returning them to Bitfinex. Such a decision could create a major legal precedent, which would influence the future management of cryptocurrencies seized by the courts.
