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.
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.
There are many options available.
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.
