It's correct. Investing in Crypto is a risk. However, the profits it brings are so great that you can forget about all the risks. I believe in the future of this market and I am still involved

Frankly speaking, I do not think that this poll is correct. A lot of things need to be considered while considering these polls like sample size.
In case, this is true (75 % Americans believing bitcoin is 'very risky'), I think the percentage will be above 95% for all over the world. Also, in my opinion the majority is not of people who like it or consider it risky, majority is of people who are neutral about it (they have no idea about what it is actually) .
