US Postal Service didn't go bankrupt because, unlike Bitcoin, it is "an independent agency of the United States federal government responsible for providing postal service in the United States." It's a government agency, like FBI and CIA.
Though the importance of USPS has decreased drastically over the years. Let's not send Bitcoin down that road.
There are like 150-200 countries in the world, and each one has its own postal service, so it's not relevant whether the USPS is an agency like FBI and CIA, because most countries don't really have an FBI and a CIA. Where I live, postal services are regarded as something close to a utility company. They just provide a basic service to the people, like the water company or the telcos.
You understand that by saying that, you place BTC in the same category as Beanie Babies. The thing about the value of collectibles is it fluctuates wildly, and the same Beanie that was worth thousands one day is worth $5 now. Prophetic?
Works of art, collectible coins of certain age and high quality, rare antiques etc etc, always go up in value and they definitely don't fall over a cliff overnight.
Now, beanie babies, that's a different story altogether.
"By necessity"? Why?
Because some parameters, when adjusted either way, work as a tradeoff. You gain something, you lose something else.
I can gain more tx/s, but I'll lose in terms of decentralization, people accepting to join Bitcoin by downloading the client, etc etc.
Not sure what you mean.
I mean that the price per KB that we are currently paying, will seem absurdly low in a couple of years. It will also seem absurd that we were allowing dust transactions to take place and bloat the database at virtually no cost.
