Just an absolute NO. Some big game companies now are still trying to use subscribers private machines to mine bitcoin in the background, some aren't warning the users they are doing this. There are many 3rd party programs out there that do this as well as quite a few programs to warn people that their machines and browsers are hijacked for coin mining. It is still a thing. There are documents on the internet of programs-publishers getting caught last year. It's not a huge issue these days with bitcoin crashing, but to try and push this concept by offering crap games while one makes high profit at the expense and destruction of someone else system should not become a reality.
People are free to try this deal, but all facts should be out in front for them to see whats really going on.
