I think it will happen sooner or later and only when the structure, the infrastructure is shaped to allow the synthesis of educational knowledge for the right sense of use for bitcoin. Feasibility of legal acceptance is slowly taking shape, and some countries are restructuring additional terms to decide. I think, Bitcoin LN solutions will come closer in practice.
It will be the approval of the time for mass adoption by the conditions under consideration.
Legal acceptance will be the much bigger issue as that is what causes FUD, which is understandable. I do however believe that legal acceptance will only slow adoption down, but not hinder it from its breakthrough eventually. Take into account that politicians also don't live forever. So those making laws against crypto today might be replaced very soon by politicians who make pro crypto regulation.
Everything could really change up but if we are basically talking about human lifespan or terms of service then this would take out ages and we are also aging too which means we might not able to see into
those times where most of those who do have position will have positive views and perceptions towards bitcoin which is really sad to think off that's why most of us do really rush up on
seeing things as soon as possible but we know on how reality works and this isn't something that can really happen in few years time so deal with it.
No I am not even talking about a whole generation (25 years or so), but rather about 10 years, maybe 15 years. Over that period of time there will be some new politicians, more modern politicians with a better understanding of technology, innovation and in specific decentralized currencies. Right now the congresses look like retirement homes. Why would they even want something like Bitcoin to succeed? Human beings are born to stick to what they are used to. That is the way of least resistance. That is where a dissonance emerges when people age but new technologies emerge and with that technology younger human beings who get used to it from their very first day of life. I think we'll see massive change within the next 10 years with regards to Bitcoin's public reception and acceptance.
