These losses are relative, as are the losses of all participants in the cryptocurrency market. Of course, the price and capitalization of all cryptocurrencies have now fallen significantly as a result of the onset of the crypto winter, which is now in its eighth month. But we know that the period of recession in this market after some time will definitely be replaced by a period of its growth. If we do not sell our cryptocurrency at the current low prices during the crypto winter, then after the market recovers, the threat of current losses will disappear.
Thus, if the North Korean hackers do not sell the stolen cryptocurrency now and keep it until the next market growth period, then they will not suffer any losses.
