Big Disadvantage is the 2% fee for outgoing payments.
After 9 months of research, my PERSONAL conclusion is that Andorra and Panama are the best options.
Andorra being super complex and expensive but no bad reputation.
Panama super simple, no accountancy, still the best way to go.(But maybe BVI etc is similar)
So the attachment thats a Panama company is useless is proven wrong. Works perfectly for a while now and with high turnover.
