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?
For me i am not regretting what i spend from 2016 even we are seen that the price was increase i am still happy that i am still get the benefits of the price increased.. it is still not late to get more profit with the price movement.. i always just use my bitcoins for important things and paying bills for my internet monthly..
It is a normal for me that we are spending bitcoin that i think i am also contribute for bitcoin just let other people to know that i am using bitcoin for online shopping or motivate other business to accept bitcoin.
