Crypto has not really fulfill that aim of serving as money so far and perhaps it may or may not (it is under probability) because the future is not certain and it is possible that some group of people are already exploring something new and different using all the loopholes of crypto or btc as a case study.
There is always a possibility as long as human exist.
That’s right, there is no end to the possibility of what we can be able to do in the future. If you go back in the last century and tell humans then that there will be such things as the technologies that we have today, they would all doubt it because they can’t see the possibility of having such technologies. But, today we have them.
So, that’s to show that there is no end to the possibilities of what we can achieve with technology. The earth is gold mine, there are still a lot to be mined and we can’t mine it all. In the future we will still continue to see more and more.
