Not sure where you got this notion. If you've read Satoshi Nakamoto's white paper on bitcoin, it's clear that what he wanted to accomplish was for money to be exchanged between two individuals without the need for a third party to confirm/uphold the transaction.

To quote Satoshi,


... and then he goes about describing the solution he's come up for accomplishing just that.

Also, note that the proposal for bitcoin was released after the 2007-2009 financial crisis, so you can also see the context where Nakamoto is coming from.

Re: mining farms now holding most of the world's bitcoins -- if true, I sincerely doubt that Nakamoto foresaw the possible 'dangers' to bitcoin if ever there were just a few individuals/groups holding the world's supply of bitcoins. Truth be told, he only envisioned CPUs to be used for mining (and not the mining 'rigs' that are used today), as mentioned in the white paper.

Having just a few groups/individuals own much of the world's bitcoins do seem to pose an issue, as it defeats the purpose for which bitcoin was created-- decentralization.

The main idea is the decentralized currency that means can do a transaction by peer to peer no third party the idea is about digital currency make a world with online transactions

I believe the main reason behind making BTC was to provide financial freedom to people , to show people that decentralised nature actually offers more than that banks do.
People would no longer need a third party like banks to look after their earnings.
Banks are good but we have to work according to their rules and regulations plus the government can peek into our accounts any time they wish .
BItcoins gives  us Extreme privacy , that means no one can know our balance untill we show them , no one could trace our transactions,

They basically made this decenralized democratic economy with the implementation of bitcoin. We all have access to it and anyone on this world can benefit from this environment. That was the main idea of bitcoin.

Obviously the primary idea of Bitcoin is to provide its users the most appropriate and easiest method of earning their livelihood without putting much efforts and just using their mental skills to cope up with the situations well. Bitcoin is best option when it comes to choosing digital currencies for the sake of trading, investment or other economic issues.

Therefore one must believe in Bitcoins and try to buy more and more of them storing these in the online wallet and securing their future indeed.

Its create to have conveniece in life and to have good ideas in different person and country.I think bitcoin will have future because its already authorized in the world as good digital money and for easy transaction.Bitcoin is like a thing that you can't imagine that exist because you can't see it and you dont have any idea where this thing will go

The main goal is to become decentralized. No one person should hold the power to control its price and its rules. Yes, bitcoin right now is kinda hard to get as so many early adopters are holding a big part of it. But I think they deserved it. They are the pioneers, and the one who truly believe in bitcoin. They entrust their money to bitcoin hoping that it will bear fruit. I think we should not worry about them or people around us. Bitcoin is for everyone. If you really work hard, you'll gain it. Just like them. Don't think that they don't work hard for it that's why they became rich. We got the benefits of this crypto, we got a side line work, a new system and a very big community. We should be happy and wait for what will happen in the future.

Bitcoin is a digital or online currency. However, its means of being made and being earned is different from the usual paper money used in the market. It's similarity as a currency comes from the idea that it can be used to buy things or pay for a specific service. Its transfer, although done through transaction from wallet to wallet, is different because what's being passed is data and not "real" money itself. Therefore, it can be used all over the world without need of exchanging it for another currency that is used in that respective country. Like many answers, it is more convenient and a more decentralized way of using a medium of currency.

indeed in this case we never know, how the vision of bitcoin. because the longer bitcoin is in great demand, it's also unknown if the bitcoin is much in the interest.

I think satoshi wanted to make a decentralized crypto currency and now we have found it. Seems that he wanted a currency which is technology based but in this time it is the world most valuable crypto currency. His creation is now successful.
