How can the site be improved, I cannot say anything to it, but I think the domain name should change. The domain is not catchy at all and it is very long. People do not want to enter sites with such domains. Even if they want to enter, they can forget it after a while. For your information.
+1. I think something like explainbitcoin or whatisbitcoin would work better and would also help with SEO.
I didn't read through the entire content, but the design looks really neat. Good work on the website design.
Very fair. Had a hard time finding an affordable domain like that but I'll keep working on it. And thanks for the kind words!
