Great to see you back on here bro. If you need a break, you gotta do it. Good thing it was just over a week. Tough luck about losing out on that ticket you had, that would annoy me a lot. Gotta just shrug your shoulders and move on after something like that. Sounds like you will be saving that amount of money by doing your own visa in the future.
So amazing to know that you at least have your 30-day visa. I'm excited for you to be back with your family. My question is, did the 30 days already begin? Or does it start once you land in Cambodia?
I have a Crypto.com debit card and have only used it in the USA. It does have an option in the visa card section of the app to enable international usage. I know that wouldn't solve all withdrawal issues, but perhaps at least let you turn some of your crypto into useable funds. Have you ever looked into a crypto debit card of any kind? There are many options, crypto.com is just the one I'm using.
