The Finnish authorities have seized a considerable amount of crypto from various crimes. Thanks to the current prices, they think it’s time to sell those stacks. The price was much lower at the time, but now, years later they expect around 75 million USD in revenue.
The majority of states aren’t ready for dealing with cryptocurrencies, neither their bureaus and authorities. They could store the crypto on the seized devices, but they could only sell it. Last year in Romania and Lithuania has sold their big BTC bags from criminals.
