Fair enough.
I know that people are profiting off of cryptocoin mining at relatively midpoint costs for electrical power, but their idea of "profit" for the amount of time and effort and overhead that goes into making it is very different from mine. People brag about making $7 a day on a multithousand dollar computing rig, and while that might be $7 a day of profit – it's $7 a day on a piece of machinery that certainly can break and will require maintenance, that increases the load on your air conditioning system, and that's just one more thing that you have to worry about keeping running all the time.
I'm pretty sure that I could shave $7 a day off of my personal expenses by eating slightly smaller portions.
Now, getting these toys because they're fun to play with – that is the motivation I completely embrace! Building yourself an extra box that you intend to be your tinkering system, throwing a VR headset on it and a nice graphics card, and first and foremost having it for the pleasure? Game on, I'm totally in. Occasionally running some coin mining on it because, after all, you've already got it and it's serving its purpose otherwise? Sure. That's cool.
I'm really hesitant to engage with the overall idea that "you can make money with it" is a good plan at this point, but "you can have a lot of fun with it," is a great plan at this point.
Maybe that just reflects my own particular priorities.
