BTC hasn't been in existence for so long, but even the short while it has existed is enough for us to understand that it has been a huge success, at first people considered it to be a bubble, or an experiment, something that will collapse if there is a major world crisis or problem, but BTC has passed all of that test and is still growing. I don't feel it is too early for anyone to judge if BTC is a success or failure, it is clearly a success, it was created by Satoshi for a purpose, and it is serving that purpose and many more as well, what else do people need to understand that it is a total success.

I don't feel Satoshi created BTC for "mass adoption", it is we the BTC users that want many people to adopt it, which is very good, Satoshi created BTC to give people a decentralized second choice to fiat, a decentralized second choice to free them from government oppression, and BTC is doing exactly that, meaning the BTC project is a success. Our wish of mass adoption as BTC users will happen sometime in the future too.

Bitcoin is one of the most successful project if you ask me, think about it this way, if bitcoin is to be a peer to peer payment currency as Satoshi envisioned it to be, there was never any possibility that people will start accepting it as that over night, there would have still been a process that will lead to such achievement.
That process stage is where we are right now, go around the world, find out, many businesses are beginning to accept bitcoin as payment for their goods and services, this is to tell you that Bitcoin is right on course to becoming/bringing to reality, the peer to peer payment currency that Satoshi envisioned in the bitcoin whitepaper.

Why do you call it failure if we're still here talking about it means it didn't go so bad after all or don't you think? Perhaps there have been changes that Satoshi had not budgeted but the protocol is open source and it will be the community that decides what should be done and what not. Let's not call it failure because it's not.

yes, I think so too. and in my opinion bitcoin is a successful project created by Satoshi Nakamoto. because so far bitcoin has provided and made good opportunities for all of us. so it's not quite right if bitcoin is called a failed project. and I also see that today's bitcoin price has increased and that proves that the bitcoin cycle is still running normally.

We are still early on the history of bitcoin, people forget that even something like the internet took a lot of time to develop and adopt, the development of the internet takes us back to 1960s and it was not until the early 1990s when the internet as we know began to exist, so even if the adoption of bitcoin is not as fast as some expected, the rate at which it is happening is similar to what we have seen other inventions going through, so bitcoin cannot be considered to be a failure by any measure we could try to use.

i think bitcoin didn't fail. if bitcoin failed, it would never have been popular in the first place.
