The best thing I like about the bitcoin is that you can use it everywhere and that its also untraceable, no one is controlling it expect you that are having the power over your wallet.
Actually it would be much better if we could use it in our real life as well,may be it will be possible in the future.Yes untracebility of bitcoin is loved by me also and fully controlled by me,unlike money in bank accounts,i can hold as many bitcoins in my wallet without any issue.
Yeah and the best thing is that we don't have to pay any taxes on our bitcoins and that makes it very unique in compare to other currencies and for the same reason people are using it.
