Cryptocurrency payment option and Pine hardware wallet, any thoughts?

[ryo]

Volatility. I'm not talking about the currencies themselves (though that is a concern). I'm talking about the communities surrounding them. When we put out our polls for if people would use a crypto payment option, what we saw was a large amount of people arguing over which coins we should accept (primarily BTC, Monero, and Eth), and good and which are bad. Let's just say those conversations weren't exactly civil. We're not interested in getting mixed up in that mess.

There are services that let you accept multiple currencies.
However, these are always intermediaries, so they will charge you a fee which adds to the issues when it comes to converting to fiat.
Though the "it needs to be usable in fiat ASAP" part is indeed quite a concern, though I do expect suppliers, manufacturers and such to accept crypto once the fiat currencies collapse, since those would the only alternatives with value.
With the exception of North Korean, Cuban, and Iranian currencies, every currency is linked to the US dollar, so once that one goes to 0, they all will go to 0.

i don't think u.s. dollar, euros, uk pounds, yens and others will collapse. mostly because they have functional economy (more or less) and central bank behind them. central bank can support currencies to a certain degree.

On average, fiat currencies that are inflationary only last 100 years each.
Once debt gets so high that governments can't pay it off anymore, it's basically game over.

100 years ago the Weimar German mark collapsed, recent well known examples of currencies that collapsed were those of Zimbabwe and Venezuela.
The US dollar is already collapsing, and since the others are linked to it, so are the euros, the pounds, the yens, the yuans, the rubbles, the ruppees, the other dollars etc.
It doesn't happen instantly, it often takes up to a decade before they go to 0, and the current scamdemic is basically the cover story to that (lots of agenda's attached to it, and the US dollar collapse just conveniently appears to be among them).

crypto currencies ... there isn't central power to support the currency when needed.

Which is actually a good thing.
Central powers are exactly what makes currencies lose value, especially if they're inflationary and just printed out of nothing.
Fiat currencies used to be linked to gold until 1971, then they removed the link, and the value started to torpedo down ever since.

crypto currencies are at mercy of investors and speculators. basically i think crypto currencies will fall seriously some point and government like power is needed to support currency.

That's a very communist type of thinking.
In a healthy economy, money is controlled by markets trading.
The only time governments control currencies is under communism, and therefore should always be avoided.
Such currency is very prone to corruption, massive inflation, raising debt, high taxes, enabling poverty, financial censorship (ask Pornhub and OnlyFans how this works, they got censored by payment processors), and so on.

most people tend to think money can hold value by itself. money hold value because others collectively think it has value or government or similar is supporting it.

In a basic sense, you can have inflationary currencies and deflationary currencies.
Inflationary ones lose value the more of it exists.
There's no ceiling for it, only a bottom.
So the more money gets printed into existence, the quicker it loses value, the less likely it becomes to fix it.

Deflationary currencies (like Bitcoin) on the other hand have a bottom and a ceiling.
There's never going to be more than 21 million Bitcoin, the more of it exists, the harder it gets to hold Bitcoin, the bigger the value becomes.
There's probably going to be a problem with that as well because nothing is perfect, but since deflationary currencies are still a very new concept, I'm not sure at this time what the consequences would be.
