It is but it is always a paper. If you are an online person like many others here. They want it differently. You just cant compare dollar with bitcoin. Someday bitcoin will be much better than what dollar is.
nowadays we can see many people not holding alot of money in their wallet..they just put their money in a card
its good idea...bcause when the wallet get stolen ..the thief cant take their money except knowing password..
in this example im sure bitcoin will be our futures
That is right. Although some uses their phone where applications are installed with their wallet in it. they cant just hack it just like that. It will be needed to have that internal passwords for you to send all those money. Plus, that phone thief wouldnt even know yet that there is money in that application. They will just format the phone for safety that they wont be traced.
