Right now the usage of bitcoin has been increasing gradually. Same time the legalised usage with the government accepting it similar to the traditional fiat too is increasing in a large scale. Maybe by now the percentage of people having small amount of bitcoin might be around 4%
Do you really believe that?
There are about 7 Billion people in the world.
4% - 280,000,000 - That is 280 million. I think that we are lucky if .4% of the population owns some bitcoin, and that would be 28 million...
1% would be 70 million.
Of course, there are people and there are various kinds of institutions, companies, affiliations, organizations and governments that could also own bitcoin - but we seem to be quite a distance from even achieving 1%, no?
I think that you can put all the cryptos together, and still fall quite short of 1%. I think that there has been some research already that support plausible conclusions that there is a lo tof overlapping between the holders of bitcoin and the holders of various other cryptos, so including all the cryptos does not exponentially increase your total number, but it could double or triple the total number who hold some crypto, perhaps.
