It is digital cash, its better than gold.I personally see and using more as something that can be seen as Gold. Now all the people are showing interest on bitcoins more than gold. Everyone have to know about bitcoins. By this bitcoin we can do anything shopping / purchase accessories.
Although bitcoin is getting more attention, but it can not be compared to gold, it's just a new currency, but and a gem that was favored thousands of years ago, nothing can change it.
Of course, although bitcoin is now more popular than gold and other precious metals but bicoin function can not replace the function of gold and gems as jewelry that certainly has a better history and longer than bitcoin.
