He is planning next superior cryptocurrency and once it's released he will dump all the bitcoins he holds

Or religion... In some ways it might be healthy for small communities. But can be rather destructive too.

0-500$

And part of population who spout nonsense which gets on my nerves...

Who cares, not lik it affects my life.

And anyway they won't learn to stop bickering...

Living of transaction cost is probably very hard.

The cost of mining is likely to match the profit made from mining or transactions. Probably even be higher.

So there would be change to make living only if you had some edge over competition...

Or for regular persons, not having to spend huge amount of money to prove that you don't have to pay anything... Just tells how broken the system is if you have to pay more to do math than the acttual taxes...

I'm happy that my government does taxes for me. Though no that I have much to tax yet.

One option is if we end up with a few large pools controlling the majority of network. They could dictate that only first TX send to network is accepted and keep list of accepted queued TXs. Also they could orphan the blocks that don't follow these rules. So in this case you could get confirmation in few seconds just by checking their publicly available lists. You could maybe even allow updating the TX if original transactions are still valid.

Though they would have to be trusted. But they could orphan each others bad blocks too.  

It's the trade-off for non-centralized, non-reversible currency.

And I can think how easily these could be given away even in bitcoin. For convenience...

The solution which might happen is to move online banking kind of system.

Just have payment processors have accounts on multiple banks/online wallets. And have them deduct funds instantly, inside the wallet/bank. The merchant should then be also able to have funds instantly.

I see that as very real possibility, not proffered one, but one that can happen for regular people.

The outcome is likely that best design will win. That is best balance of cost and hash/W. And it's really about overall design, the sweet spot of speed and power.

So in end it's probably a few corporations making the miners for own use. Though the capital is good questions, probably those who have the most forsight now to store some for private use... 

Moore's law itself does scale further, though there is walls with gains and prices.

You just need to add more chips for Moore's law to work. Though this is costly and gains aren't very good beyond some point.

It can pop, but that is when bitcoin goes out of use.  As said, it's not a bubble as in financial bubbles.

So United States of America is less democratic as they don't have democratic or Republic in it's name?

You are not to underestimate the effectiveness of sneakernet...

NK is bit on authoritarian side for this forums preferences I think...

Umm, since when has USA government cared about what is legal? It's war on terrorism, anything goes...

If they do it, it's legal for them... Or at least the consequences are very minor...

I think technical attacks would be much more affordable.

If you can stop BTC from working or hinder it's operations the value of it is lowered. So just invest in hardware and use it in harmful ways...

There is really quite a lot of options and multiple attack routes if you start thinking about it. Why not just write more of those nice viruses to destroy wallets, ddos the online services and maybe even nodes in network...

Why would central banks adopt bitcoin?

Why not just come up with alt coin and start using it with governments, big banks, etc.? Or multiple alt coins.

Replacing fiat with bitcoin is stupid for them, when they could as well replace it with their own currency... And as long as they have governments behind them, large part of population will follow.


Add:
Apart from ofc destroying it, how long would the system last with systematic attacks of majority of hashing power? Double spend is small worry if blocking transactions and generating bloat in chain is other option...

So how much money and what things have been lost to bitcoin?

What kind of cake could you make for 2BTC... And who buys one for 4BTC?

Just like with ponzis and pyramids, become your own house

Though 2BTC is too low amount for that...
