1. Why did you create a technology as big as blockchain and bitcoin and gave it out for free
Satoshi did not create the technology out of a selfish interest; he created the technology and Bitcoin for everyone in the world to use, and despite his absence, the purpose for which he created the coin is still a success.
6. Wait! Are you still alive? Or you died of earthquake in the North?
If he's dead, who do you then expect to come and answer this question? But perhaps even if Satoshi is here with us, he would not respond.
7. Are you a man or a woman or a group of people?
LOL, these questions is dumb. What will you do with such information? 😂
8. Do you have any regrets in creating bitcoin. I asked because a scripture said that God regrettable creating man.
Satoshi is not God, and as long as Satoshi's vision for creating Bitcoin is fulfilled, he will not have any regrets.
15. Why is halving 4 years circle and not 2 years. Is it related to the world cup 4 years interval?
That's because halving is supposed to occur when 210,000 blocks have been mined, and these are completed approximately every 4 years.
18. When do you intend to re-appear as Satoshi Nakamoto?
He will not, because he doesn't have any need to do so and his technology is still efficient.
20. Do you have kids did you teach them about bitcoin, are they into bitcoin now?
OP, Satoshi did not pass any interview that I am aware of, and really, you don't expect Satoshi to come and answer all these questions. But because Satoshi is a human, he could have children that we are unaware of.
