Despite them being a EU member state, they don't use Euro as their official currency. Since they have their own currency being the Zloty which is considered stable, but even if you have Euros or US Dollars for converting to Zloty: does purchasing power hold up since both Euro & US Dollar possesses a higher rate? I figure that Warsaw will be expensive due to it being the capital, so that is expected.

Apparently in Japan, their Apple Stores just display all their devices without any security tags on them since it’s built within a trust system where an individual is expected to not shoplift (due to shaming culture) as public face and reputation matters to them along with heaps of CCTV and stricter laws. However, try doing the same thing in New York or Seattle and see what happens…

I know that Euro is the second most traded currency but it doesn't have the #1 spot because of the US Dollar (which is printed on top of piling debt by the way) since oil is priced in USD per barrel instead of quoting it in EUR per barrel (since the US has monopoly on oil).

Money printers for the USD are running constantly, going "BRRR" and have a high national debt. They're putting themselves further into that hole whilst printing more cash. What about the Euro? Is it even printed that often 24/7 or controlled to print a capped amount?

The only way to really Euro become superior is to incentivize it on a international scale (more than the US Dollar) on getting countries to accept & trust it more (but USD accounts for 60% of global commerce) so the Euro has A LOT of catching up to do on that.

Does the EU really have power or control over OPEC (Oil)? If they can grasp monopoly over the Gulf states by convincing them to price every barrel in Euros: would that strengthen the currency? The British Pound is the former global reserve currency before the US Dollar.

If European travelers stopped converting EUR to USD, only using EUR for international travel towards currency exchanges: would that increase the demand for it since US Dollar is literally the default for A LOT of countries (even "third world" ones) in terms of payment.

Arbitrary numbers regarding forex aren't an indicator: so what if 1€ is worth more than $1? It's more on PPP and trust, so with a stronger Euro traveling abroad (including the Americas): does that make it cheap for you to visit as you're able to buy more than they can?

I may travel to Canada in the future, but these are the currencies I have:

• Kuwaiti Dinar (1 KD = C$4.50)
• Omani Rial (1 RO = C$3.60)

So, they are worth more in face value. The question is: will money changers in Canada accept or recognize them on directly converting to CAD despite these currencies being uncommon? Also will I really be allowed to bring either 5000 RO (C$18,100) or 2000 KD (C$9,025) in cash?
