Dear
@Astaruk,
for svaings I don't recommend you classic offshore Banks like let's say Belize.
You need to take a look at the jurisdictions that still provide you with transactional banking.
When it comes to Crypto you may be need some workarounds because offshore+crypto is huge red flag.
What you can consider is a jurisdiction like UAE that grants you along with the company formation a residence visa and therefore the local UAE banks are open for business and don't consider you non-resident.
Even if you want to have everything under personal name - it's a straight forward and reliable process.
You did not mention your current residency. Don't forget that simply an offshore bank account doesn't help when it comes to CRS reporting. As a high tax country passport holder you have to consider this.
Don't go for any offshore bank that charges you 1000$+ for account opening and is not transactional at all.
