50k Budget, New to Mining

[ron8]

Hey all, I’ve been interested in mining for a while now, used to GPU mine but nothing substantial. I have around $50k USD saved up, and I’m ready to start mining like a big boy. Does anyone have any advice on what machines I should purchase? I’m looking for something predictable, and that will hold its value. I was looking into the Goldshell AL box, but from what I can tell, once the bitmain AL3 releases, the AL box will be practically useless. Any help is appricated, thanks all ; )
