The advantage is you cannot misplace your money because if you have an account you cannot dissappear your money easily.
Ain't that reasoning just the same with banks? I dont want it to be the same with it. I get out of that industry just so I can manage it by myself. You could still misplace the private key or log in details or your computer could get wrecked and you will lose it all.
Best we should still have the hard copies of it.
Advantage is the price will keep rising as bitcoin goes lower and lower in number.
since bitcoins was created to eliminate banks then we expect for less conflict on our transactions. we can pay our bills online all the time with bitcoins and no need to spend our precious time in falling in line in designated payment center. at the same time as above comment said the bitcoins price just kept on rising so the advantages are more on bitcoins rather than saving your money in a bank or keeping it. less hassle and less effort while earning at the same time if we'll be lucky enough it will make us become rich or richer.
