already presume that theres no update nor progress about such issue with this Boyko.
That's correct. PBmining was one of the largest and most popular cloud mining services back in the days. As always, these ponzi schemes don't last for ever since there isn't an infinite pool of noobs within the market cycle(s) they operate in. Thank bear markets for eradicating these bad actors.
According to the hashrate stats on their site they were quite a significant miner, yet no one could locate their mining addresses with how transparent Bitcoin is. They (like most other cloud mining services) always ignored people who asked for their mining addresses, and they had a good reason for that. It was an empty scam hole.
