Please where is this studies actually coming from? I think an important country is missing here which is India. In terms of awareness and ownership, Indians are well ahead of Indonesia. I am also not to sure of South Africa being included in the top list.
But from what I heard India was banning crypto, so it cant be included, and I agree that the percentage is too high, its only small portion of Indonesia really engage and invest in crypto, in Asia crypto is very popular, and crypto is more popular in third world countries and developing countries, for Europe the investors prefer the stock, they prefer more traditional investment
