My "no" was not in terms of dissimilarity but in terms of "the worst of both worlds". You make it sound like it's a nightmare scenario when it is not.
Either shopping at a bazaar where all the dealers use different fiat money & you have to exchange money all the time is a nightmare, or it's not. It's certainly not as frictionless as everybody using the *same* kind of money, no?
Given a choice, which would *you* choose?
Well, there are like 200 countries in the world. It's not a disaster if people use 5-10 cryptocurrencies.
Why would anyone hold bitcoins (the tokens), if no one uses the particular instance of blockchain (the Bitcoin blockchain)?
Store of value of BTC > Store of value of altcoins
Wouldn't LTC be the gold standard (since everyone uses it)?
No because it is understood that in the long run, the increased use means a coin with a very bloated blockchain that will become increasingly difficult to transact with, or have a properly syncing wallet.
The idea of disposable blockchains / altcoins, that serve a role for some time and then die, should not be ruled out if scaling issues with bitcoin make tx spillover into altcoins.
The only reason exchanges don't let you convert shitcoins directly into fiat is because legit exchanges don't want to bother. If an exchange can legally handle fiat, it can legally turn shitcoins directly into fiat. Without the pointless extra step of first turning them into BTC.
Most exchanges don't support turning all shitcoins to fiat, only a few. And even then their trading pairs are very thin in volume so it's preferable to go through BTC/shitcoin pair before getting fiat. If you can't even dump a few BTCs worth of shitcoins without crashing their USD price => goto BTC pair.
Fiat is the least volotile, just convert straight into fiat. Hey, make it easy on yourself, use fiat throughout & avoid all this rigamarole.
It depends which fiat you are talking about. USD/EUR/GBP/CAD/AUD etc, are relatively strong currencies. But what if you live in places where after 3-4-5 years, you have huge devaluations, say your local currency was 40:1 with the USD and then you go to 100:1.
For these countries, where inflation is a given tendency, money tends to move to safer assets, like gold, real estate, even BTC. Of these assets (gold, real estate, BTC), only BTC is directly spendable as money where you can actually open a browser, order things or services, pay with BTC and voila, you are ready. This gives it a tremendous advantage.
Not to mention capital controls... from where I am right now, I can't transact internationally with fiat as my government has restricted my right to do so. I can't even buy 10$ worth of stuff from some chinese eshop if I wanted to. However, with BTCs I am not restricted the same way. So when a government can flip a switch on and off on my ability to conduct international trade, that's a huge problem right there with fiat. When a government can confiscate money from my bank account, again huge problem. And the list doesn't end there.
Not too familiar with NXT, but doesn't it have its own tokens, imaginatively called NXT?
It does.
