Local media sources reported that the "NiceHash" cloud mining service based in Slovenia returned 60% of the 4700 Bitcoins that were stolen in December 2017. The company promised that it would return the missing coins to its customers shortly after the news of the change was made public.
The coins were worth about $ 65 million at the time of the hack. Because the price of Bitcoin has fallen so badly (about 70 percent) since hacking took place, interested users have lost the potential to make thousands or even millions of dollars.
