One of the great things about Bitcoin is that the future value of Bitcoin is much higher than the present value. Therefore, when purchasing anything, we have to consider the long term value of the thing. When I buy something, I ask myself if the future value of this thing will be retained, or even grow. We don't want to buy something and see that value decay immediately. Better to HODL. Now when I buy something I research it much more thoroughly and I look for things like lifetime warranties. A good tool that will last a lifetime is so much better than a cheap tool that will break quickly.
The Bitcoin community on Reddit is mostly garbage in comparison to SN, but there are still some good communities there. One go to place for this very topic is /r/BuyItForLife/
