Well, those things weren't decentralized. ...
That's what I was going to say. There really are no precursors of bitcoin. The examples you gave were attempts to make traditional systems work in a digital environment. Bitcoin is a digital native, and when combined with the lack of central authority it is truly different. It is a revolutionary development in the evolution of money.
This implies that the technology itself was not that important but rather the implementation and momentum.
Makes Bitcoin seem more fad than revolution with that narrative. For me I would rather hear that Bitcoin implemented something in the algorithm that was truly unique and revolutionary that until that point represented a fatal flaw that would not allow the distributed momentum to ever take hold.
I would say that the protocol is brilliant, but does not include much revolutionary code. Except for perhaps the blockchain, It is more of a revolutionary system. As long as it is the fastest, safest, and cheapest way to send money it is not going anywhere.
the credit cards are the cheapest way and the "safest". BTC propaganda is spreading a lot of lies regarding to this thing. BTC is not free and not safe. a lot of hackings, a lot of problems.
Bitcoin, especially in the early days, so an alternative for those who do not like to trust the government, central bank, or a third-party institution to maintain the value of the currency and ensure the user transaction.
In Bitcoin, all of it was replaced by using mathematical calculations and cryptography.
Each transaction in bitcoin will be tested through a cryptographic system that is spread across a network peer-to-peer. It is estimated, there are tens of thousands of systems that also perform this test.
Bitcoin is not free from theft. However, any stolen bitcoin will remain recorded in the system so that when used for transactions were, in theory, will always be tracked.
Bitcoin decentralized system made many refer to it as the Internet for money. If the Internet is revolutionizing the way the global communications, Bitcoin is believed to change the way the world uses money.
