On this one we really disagree.
Funny because I think we agree.
Took me one year to understand that Bitcoin is not going to be a world currency.
I realised that not so long ago in fact.
Others will have that niche . If it does succeed, I see it more as a store of value like gold.
Sure, you could buy with it something at the store but most wouldn't.
Yes, bitcoin will be (at best) a *reserve currency*. But it will not be adopted by mainstream as THE reserve currency, however, it is practical as a reserve currency for everything unregulated, half unlawful, and dark finance. Its transparent nature, however, is maybe not the best thing for that.
For the moment, with block chain tech, no linear block chain tech currency can ever hope to be a world currency on chain, and if you take it off chain, you have banking. You need tree like structures and not chain structures in order to even hope to become a world currency.
Yep.
ATM there are dark technologies that uses zero knowledge (zksnarks) and could be even an end game on the subject.
