But isn't the point of a CryptoCURRENCY to be used as a currency? If the coins get delivered, that's nice and everything is good up to that point. But then the coins get sold by the citizens for their country's fiat, and that isn't doing anything to help their situation. In fact, they are just hurting their economy even more by bringing (soon to be worthless) digits into their country, and "steal" some fiat money from other people who buy it hoping that it can change the bad state of their economy long-term.
For me to consider a countrycoin as legit and not a scam is when the people launching it are going to long-term support the citizens of the country to actively use it as a currency. Work on projects (with the help of the devs), try to offer goods and services for it. Not just give it to them and tell them to sell it so they can have some extra pocket money, and then that's the end of the project for the devs? And the citizens will be left with a soon-to-be-nothing in their hands. Sure, I get your point, it is still free money and noone (except bagholders) is losing any money, but... if a dev is "claiming the name" of a country and making a country coin with it, he/they should have the dignity to treat it for more than that. After all, the devs make a lot of money with this because they can dump as they see fit. They should have connections to non-governmental organizations, official, public engagement with the citizens over the internet, a ton of translators etc...
tl;dr country coins should aim to help a country and not be treated as pump and dump; they are abusing the name/economic state of the country to launch a project for quick profit, bringing false hopes for some citizens, which is scammy
I can't disagree with most of your points, but when you think about it, what percentage of cryptos have a real chance of being used as a currency? Many don't even pretend to be used as a currency. I wouldn't call them scams. I'd call them really bad ideas, but not scams.
As for the nation coins, there are situations where some could possibly be used by the community. Maza, for instance ... not that I think the creators are doing a good job (quite the opposite), but it is possible that Indian groups could take it up. Payu certainly seems to be trying to get merchants to adopt it. There is also the possibility that a nation coin could be adopted after a giveaway, even if just small scale with a handful of local merchants.
If you ask me if this is likely... nope. And if you ask me if nation coins are a good idea, I'd say nope. But I wouldn't automatically blacklist all of them, thinking they are all automatically scams. I'm against this blacklist/shitcoin group thing to begin with, but there is a real danger in saying coins are definitely a scam, before a scam is even committed. It'd be like arresting someone who looks like a criminal, before a crime is committed.
I expect the nation coin fad will die out on its own, regardless, after several nation coins have a problem with their airdrops. Or a coin doesn't do an airdrop at all. I think common sense would indicate that very few of these coins will work out or are worth holding onto longterm.
