Bitcoin as an idea is very interesting but, in actual function, it's a scam. I wanted to learn more about it a year ago and so bought some mining ASICs. It doesn't take long before you realize that your magic money printing device was sold to you at a cost that means you will invariably lose money. Which makes sense. If I have a magic money printing device, why the hell would I sell it to you instead of running it myself?
Um, because of reality? In this case, cost of capital:
If I can make a machine for $900 that generates $100/year forever, I get an 11% return on capital.
If I can sell it for $1000, I get an immediate return of $100, and can build another machine and repeat the process. At one per day, I make $36,500 in my first year.
If the risk free interest rate is around 3%, the second plan is worth 10x as much as the first plan.
