The simple reason why so many people love Bitcoin is because of its decentralized nature, because the coin is based on proof of work and the possibility of getting profit from the coin during bull season. Most people are investing into Bitcoin because of the profit that it generates to them and as long as Bitcoin is going main stream and demand is increasing, people will continue to invest.
Thats definitely one of the very first, its source codes, Bitcoin being decentralized and the fact that, Satoshi Nakamoto completely kept his/her/their nature completion of the picture.
You iust get that confi that, aint no attack from now where and someone isnt going to jump on Satoshi Nakamoto someday and be like; how do we reset this or stop that and have everything chattered away or perhaps, revamp for whatever reason there might be.
The idea behind Bitcoins creation wasnt profit oriented but, to make finance much more easier for mankind, thats why its so good.
