Feedback Request (ditching US/USD)

Hi all!

So I'm a UK based founder who started Yozax.com - we are a social networking service and also run a free eSIM service (with a huge waitlist ATM but a pay to skip option)

We are trying desperately to reverse our American partnerships and now have 95% based European systems but we still run our core cloud infrastructure on AWS (Amazon)

We have switched our primary network carrier to drei Austria (3 for us UK folks) but we still rely on local carriers obviously for our roaming agreements.

Now my main question is, what currency is pegged to take over USD? We charge currently only in USD as we are a pretty global service and it's always been the reserve currency, should we switch to Euro? Do those based in Poland/Switzerland etc have aversions to paying in Euro? I know here in the UK it's a bit of a turn off.

I'm trying desperately to get us off the US services and USD currency but a bit stuck on what is supposed to take it's place or what the majority think "should" be taking its place!

Any feedback or advice on what we should be doing here to help out fellow union (albeit, we are no longer with you, but I think we all agree that was a mistake...)

Thank you!
