Although bitcoin is very difficult to physically steal (in fact there are many cases of losing computers or bitcoin wallets), it is the victim of hackers. Besides bitcoin is quite slow and transaction fees are high, so saying bitcoin is the complete version of money is inaccurate.
At the moment bitcoin is a market where people invest and make a profit, it would be more correct to compare bitcoin to gold.
I think I can say to your point here.
One important characteristics of money is that it is generally accepted by every one in the community or society but bitcoin is not yet known by all the people. Bitcoin is still struggling to go to people's accepting it, it is still very volatile and money isn't. I think that we can look bitcoin from area that it is digital currency purpose.
