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.
I think the people who know bitcoin are quite popular and during the pandemic when people were at home and exposed to the internet more and more, bitcoin became more popular.
The main reason to keep people from turning to bitcoin is that governments don't like bitcoin and they often defame it. Besides, some of bitcoin's shortcomings also make it difficult to become a currency (a lot of people say that bitcoin is slow and transaction fees are high).
