I believe and I do not intend to be racist, that genetics plays an important role in this IQ. Now, I really have no idea what my IQ is, how is it possible to know? On the internet there are a lot of tests, but most are very few reliable, I do not know any that is really valid. I have also tried to explain other people about blockchain and cryptocurrencies, but I have obtained similar results when I tried to explain basic economics to a socialist.
