How many members here trade, hold or had in the past CryptoCurrency?
In each country, at least 15% of the population and even more, so these people are likely millions. And some are hidden traders and millionaires.
Nah, the numbers you give are obviously too big compared to the real ones. 15% from each country gives you more than a billion people. The estimated number of people using bitcoin is less than 30 million, which means you are about 30 times wrong.
As for this forum, I suppose about 70% of its active users have at least some of that experience. I am a long-term investor. I tried the short-term thing and screwed up. I didn't try trading, but I think it is even riskier and harder.
