I think it's impossible. A lot of things should be explained to have some basic understanding of it. Simply put I say that this is a decentralized currency that exists on the Internet. No one controls it, it has fixed amount, and it's issued by computers that solve difficult mathematical algorithms. That's the easiest definition I came up with. But it's very superficial
Defining BTC is definitely possible.I got into crypto early 2017 and got pretty stuck trying to understand it. After 6-8 weeks of research, I created
Decryptionary.comDecryptionary is the simplest crypto resource. It explains what "bitcoin" is in approximately 100 words. It has visuals. It also has a dictionary with 200+ other entries.
For the guys who want to learn how to buy their first BTC or altcoins, I have super simple and visual walkthroughs.
For the guys who want to figure it out themselves, I have word lists by subject.
It's a growing thing. But I think it will help others.
