Considering you could have used the money to buy bitcoins and essentially double your money instead, what purchases did you make this year that you are now regretting?
If you knew what you know now, would you have been more frugal with your money?
Actually I spent a lot of bitcoins in gambling and more in buying domains, actually I am a seller of bitcoins and earn some fine profits with this but honestly had I just saved the bitcoins rather than buying domains with it for people then I would have earned much more.
