afaik its complicated to create bank account in country where you don't live no? I always had to provide proof of address or something, from that country, which is complicated if you are not millionaire with property here and there.
Not super complicated with fintech providing multi currency accounts.
You can also get e-residency in many countries like estonia, lithuania, etc and avail their government services digitally. You will be able to open a bank account and sign stuff.
Okay, but in comparison whats easier, spend 3-5 hours to set up a crypto wallet or few weeks investigating e-residency, applying for it, then opening bank account.
People think that e-residency is just a breeze to do, but people who try, discover that its much harder than thought. Still easier than normal residency, thats true.
There are plenty of fintech companies that allow you to keep money without much hassle. Also, when you are on vacation, consider paying a visit to a bank, it's not that hard.
