Why do people want Bitcoin?
Bitcoins act as new currencies in the digital age. It can cross borders without any banks or governments.
The recent boom in Bitcoin may be great news for those who put money here early. But it also made it possible for Bitcoin to become a distant currency.
I can now use my Bitcoin number to buy stuff at Overstock or book a hotel at Expedia. But if I use Bitcoin to buy $ 25 on the Overstock today, and next week Bitcoin prices will increase fourfold, I'll feel that stock is $ 100. If Bitcoin loses its price, at least I still have the stock to use.
Bitcoins are considered as a kind of asset, instead of currency, with great profit expectations later on.
Just like you said... but in a simpler term "decentralized". People liked bitcoin because it is a decentralized currency who's value fluctuate high nowadays because of high demand. And with that, it is considered as an asset. It also offers a great way/s for investing money since the return of investment is indeed high. You can buy the stuffs that you want using BTC, but since BTC is not acknowledge everywhere, you cannot use it conveniently in the real world. Especially in those countries who do not regulate or establish Bitcoin
BTC yet.
