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?
Well, it's very good question.
I started one online business this year.
I didn't have enough funds to cover all expenses, so I sold some Bitcoin funds from my wallet.
My business failed but BTC value is much bigger now

My bad luck!
