Sure. Like Google has been succeeded. Diamonds have been. Gold. Kahlua. Bailey's. Microsoft. Amazon. Facebook. This list is endless. The point being that "first to market" has remarkable staying power. Not that BTC can't be replaced, but that it is likely to remain dominant for a looooong time.

You kill your own argument here with temporal issues. You even note it with "currrent blockchain design". You're saying that in the future, the system will still be limited by it's present issues. That's nuts.

Maybe I have misinterpreted your post, but no one is saying that BTC is the ultimate currency, anymore than Bailey's is the ultimate Irish cream, or Amazon is the ultimate shopping site, or anything else. But soooo many of it's "shortcomings" count on it being static, and everything else changing.

Yahoo was the leading search engine and web portal, Google succeeded it. (Yahoo still exists, but without nearly the market dominant position it once had).

MySpace was the leading social media site, Facebook succeeded it. (MySpace still exists, but without nearly the market dominant position it once had).

There were many e-commerce websites that started before Amazon, Amazon succeeded all of them.  Most of them don't exist at all any longer.

Microsoft certainly wasn't the first computer operating system.  Microsoft succeeded those earlier operating systems.

Clearly, nothing can be gold or diamonds except gold and diamonds. However, there were many things that were used to store and transfer value before gold and diamonds succeeded them.

The list isn't as endless as you'd think.

Being first to market is significant, and the network effect makes it difficult for a cheap copy to usurp the existing infrastructure.  However, if something significantly better (or better managed and marketed) comes along, it will almost certainly replace bitcoin.

It seems there will be more scarcity for Bitcoins as near 2040. But i think more decimals we will be using at that time...

Bitcoin supply today (2013 December 29):
Approximately 12 189 325

Bitcoin supply in the year 2040:
Approximately 20 917 968

You are suggesting that 20 917 968 is less than 12 189 325?

Certainly.

So you are suggesting that hostmaster has some reliable ability to predict how much of bitcoin will be in circulation and how much will be "stashed away" 26 years in the future?

And what is so magical about the year 2040?

Will there not "be more scarcity" in 2014?  How about 2020, or 2030?  Will scarcity then decrease in 2050?

You do need to be a prophet to claim the increasing scarcity of bitcoin, since there is no way of knowing if bitcoin will continue to be desired, valued, and used in the future.  The fact that something is in limited supply does not guarantee that it will continue to be used as a store of value.  The teeth in my mouth are of limited supply, but they don't appear to be storing much value at all.

hostmaster made a claim that "scarcity" would be greater in the future without specifying that the declaration was dependent on the assumption that bitcoin would gather steam.

I pointed out that there is no guarantee that "scarcity" would be greater.  (It is entirely possible that bitcoin won't gather steam, and as such "scarcity" could be lesser in the future due to the increase in supply).

The fact that you assumed that bitcoin would somehow gather steam in the future explains why (as you've pointed out) your declarations "make no sense".

Now, if we choose to discuss what will happen to scarcity if bitcoin "gathers steam", then I would agree that the assumed increased demand would logically lead to an increase in scarcity, but to declare that "there will be more scarcity for Bitcoins as near 2040" regardless of the future popularity of bitcoin would be a false statement.

Will we be able to measure or account for the coins that get lost and therefore deflate the system. Hopefully it will be an insignificant amount.

Deflation or inflation, I don't think it really matters, because value or price is just a relative issue. Anyway, I was wondering about Satoshi's strategy and recently I saw some resemblance between the growth in amount of BTC and the world wide population ... watch the green line and 2040. Maybe it's unrelated, maybe not.
