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?
Whatever i had this year were all in bitcoins and i did not use any of them for a reason that should make me regret it. I did not have any cash as i'm not on any job and a student and i spend my bitcoins on only important things this year.
