40%-50% of people in the Earth were owned bitcoin by 2020. Because most of the people were still scared to scammed, they always thinking that online or digital transaction were scam especially to the old one. But I'm still hoping that most of the people in the Earth were accept the value of bitcoin.
This is a very large figure for such a period of time. To date, many have not even heard of bitcoin. The more real figure is 5-10%.
