Why Bitcoin still remains the leading cryptocurrency in the world.

[Ziskinberg]

It is known over years and now that Bitcoin is a mysterious and some kind of digital currency that is not well known how come about and only the creators of it knows and control it and is a supernatural creature and it like is an idea or vision of the creators to control the planet after God.

You can never find it mysterious if you know the history of Bitcoin. And please don't include any religious belief here as they are not a part of this as Bitcoin was created by someone who only has the gift of such creativity and vision. We can sometimes think about how this happened? But as we understand the situation, digitalization comes without realizing it will hit the market the same thing that we never expect from Bitcoin.

The idea is so brilliant, so why not take this and enjoy it without the control of other people like the government? This why it gains more attraction and interest from those who want freedom.

..control it and is a supernatural creature and it like is an idea or vision of the creators to control the planet after God.

I am really thinking about what you said and I cannot get this  
Btw, simply, besides things that have been explained by @_act_ above, there is something simply like:
-  What will everybody say and know about cryptocurrency at first? the answer is Bitcoin.
- Some people may not know what is cryptocurrency, but they will say oh, yes, when they heard about Bitcon. This is related to the popularity
- Why there are always FUD spread by most people around the world about crypto? Why should be Bitcoin? because Bitcoin is number 1.
- and more importantly, we have been seeing how the process and progress of Bitcoin so far, its up and down, its followed by altcoins, the value, the market cap, and anything about Bitcoin.

Bitcoin remains the leading cryptocurrency because bitcoin is the first decentralised cryptocurrency with a superior blockchain. Bitcoin is not an imitation of any currency or cryptocurrency.  It will always lead other crytocurrency because other cryptocurrencies are trying to imitate what bitcoin has .

It’s the granddaddy of all the cryptos! The first born crypto and then “variants” a.k.a. altcoins such as Ethereum, XRP, DOGE, etc., developed and keep growing further, then expanded into NFTs, DeFi, metaverse, etc.

No one can control Bitcoin anymore even the founder himself. It is being developed and deployed one time and nobody can control it anymore. Not banks, government, etc. Bans don’t work either.

You will perhaps be thinking as well in a different view.

 - It is decentralized - nobody is controlling it
 - the most valuable coin among cryptocurrencies that gains interest from the investors
 - legally adopted by some countries
 
Plus, we can't deny that Bitcoin is specially created for a special role, unlike these altcoins.

Unlike the traditional currency where you use credit or debit cards that are controlled or tracked by a third-party such as government authority, transactions in Bitcoin do not involve a middle man. Every completed transaction is recorded in a Blockchain.
