As we all know that Bitcoin is firstly introduced to us for it's convenience and numerous benefits. Being banked or underbanked, we can still enjoy the benefits and the accessibility of transactions as long as we have access to internet. Another benefit also is the anonimity it gives to people(although some would probably say not totally). By this, it is only right to say that Bitcoin has the potential to completely transform the way we think about money and finance. Compared to what we traditionally knew about finance, cryptocurrencies and bitcoin allows an individual to participate on the global economy without much requirement that otherwise it would be impossible.
I think it is not really about age, or not even about disrupting at all, it is about do we need it? I mean if bitcoin is capable of disrupting the current financial landscape and there are millions, even tens of millions of people in the crypto world, does that say anything about fiat world? I think that should be what we should be focusing at the moment.
If the fiat world is bad enough that people are moving towards bitcoin then maybe the problem is not with bitcoin but the problem is with the financial landscape itself? We should try to fix that before we try to attack bitcoin to be fair, that should be a lot more valid and a lot more important to all of us.
