According to my knowledge from a research article of which I got from a reliable source I understood that the amount of Bitcoin which is in circulation is far less than the total money available in circulation.also the Bitcoin ecosystem is not large enough to cover liquidity properly Since mining is not promisingly efficient how will enough Bitcoin get into circulation? Such that everyone has enough Bitcoins to cover their net worth
I am not sure whether I understand your post, but are you asking whether it is a problem that there is less Bitcoin in USD value than there is USD in total? The second part of your comment probably refers to maximum transaction throughput compared to global daily transaction demand (or for now USD transaction demand)?
You have actually detected a major problem of today's economy.
There will always be more FIAT USD than there is real value justifying the amount of all the USD money printed. The result is inflation. Real value desperately appreciates, but not in value, only in numbers, following the pace of the money printing machines as much as possible. At some point the market realizes that no matter how much money is printed, an asset relative to other assets doesn't increase in real value because of that.
The question is not whether Bitcoin can cover all USD notes out there as of yet. The question is whether people want to switch from a money that can infinitely be manipulated and boated up to a money that can't be. If I pay you 100k USD for your apartment and bread costs 10 USD, you are in no different situation than when I pay you 200k USD for your apartment and bread costs 20 USD. With FIAT money you can play that game infinitely, and infinitely dangerously because it is prone to collapse and not all asset prices adjust according to some money printing logic, evening out dangerous economic effects.
That is why Bitcoin is interesting, it is a system outside the existing system. This means that if Bitcoin is globally appreciated by all people, no national currency could be printed to easily buy Bitcoin up because it would have its own value that could appreciate beyond M0, M1, M2 and M3 of a national currency.
