@user9823671 every incorporation in a black listed country is not a good structure for almost any business which wants to do business with EU companies. If you charge end customers this may work, but if you want to charge EU companies they won't pay to a Nevis company, as Nevis is on the non-cooperative OECD list and therefore invoices are not accept by a lot of EU tax authorities.
In my opinion structures in Nevis and a bank account in Nevis only make sense for asset protection issues and for the "endstation" of your offshore money to store it, because almost no authority will be able to seize your bank account there.
But still, I wouldn't trust the bank systems there... their pages are mostly wordpress pages with custom made customer panels which access their banking database to display their balances etc. (once it was possible to see the plugin creator at belizebank.com/wp-admin and thebankofnevis.com/wp-admin and pacificprivatebank.com/wp-admin, but sadly i forgot to remember it, all I can say it was the same company, as they all had the same logo in the admin panel login. The Vanuatu Private bank (pacificprivatebank) still didn't block or hide the wp-admin page so you can still see it's a wp (pacificprivatebank.com/wp-admin), maybe their logo will occur there one day again when updating the installation. Will write a script to detect this change, because this would be a good info for me to know again. Belizebank and Nevis bank at least hide the wp-login.... belizebank has a whitelisted ip range to access their wp-login, so no chance anymore, but nevis just moved to a crypted link, so possible to know again after crawling)
I could tell you more funny stories about other offshore banks where I found crazy ridiculous XSS with high vulnerability potential. But that's not the topic. Just wanted to state my point of view that these banks in these jurisdictions are mostly unsecure and s**t.
And by the way everybody knows what is happening at Choice bank right now, so I really would fear that this will happen within the next 20 years to a few banks within these jurisdictions.
