Look, I am not one that believes that bitcoin is going to become the premier or even "a" premier currency in the world. I do however believe that bitcoins first mover advantage is a massive advantage. Bitcoins power (just like gold) comes from peoples belief in its value first and foremost. That isn't going to change, its going to grow. Second, the applications being built on top of the protocol are going to more and more valuable. Just like html was to the development of the internet. We truly don't know where this technology will become. Probably something we haven't though of yet.
But even if bitcoin is a little bit of a lot of things - frictionless payment system, currency, store of value, remittance vehicle, collapsed state secondary currency (see NEO/BEE in Cyprus), trade payment system, trust and will platform, it doesn't matter. There are only 21 million of these coins. And there are 7 billion people. It doesn't take a lot for bitcoins price to be in the high 5 figures or 6 figure range. And when it gets there volatility will actually be a helluva lot less too.
I think that we largely agree with one another.... and my previous discussion point about the deflationary aspect remains a concern of mine... but I am NOT of the belief that it is fatal to bitcoin.. .at least NOT in the early days... And the dynamic of bitcoin may be quite interesting in 20 years... to see if it holds any niche at that time.
Nonetheless, I agree with you about the exponential potential of bitcoin. Frequently, I like to use the example of gold having a 6.5 trillion dollar market cap, and BTC has less than a 10 billion dollar market cap. The dollar has something like 15 trillion dollar market cap... Anyhow, BTC could take some of that functionality and value... even less than 1% of the combination of the two, would leave bitcoin with a 200 billion dollar market cap - which is more than 20 times its current market cap. And, there are a lot of other potential uses for bitcoin to take value from other markets, including remittances and the currencies of other countries.... and we could get to those points fairly quickly.... less than 2 years...
