It’s basically an algorithm someone created and started selling it. You are mining nothing, you are mining a server that someone created. It’s basically a game with real money. They changed the “algorithm” when someone cracked it. At any point the creators can decide to shut it down or just “take it all”
It’s a scam, the type that even has big banks falling for it now.
