Let's be real here. There is nothing legal about earning money through a Seychelles company, hiding it in Euro Pacific Bank, not declaring, not paying tax, and living in Denmark.
What you are doing would be a direct violation of Danish law, both in terms of taxation and in terms of not doing proper book keeping. If the Danish authorities find out about it, you're looking at financial penalties and possibly jail time. Secrecy is not sustainable especially against a competent and aggressive tax authority like Denmark's.
If you don't want to pay Danish tax, leave Denmark. If you have an EU passport, Malta and Cyprus are popular destinations for people who make a living entirely online. Costs of living are lower too so your $5000/month will last you longer.
Facts
Simply relocate to tax friendly country. I still don't understand why anyone with ambition would just stay put and risk it all to setup something offshore.
I guess many of those people wouldn't have a clear idea that they are at risk. A lot of people will ignore the fact they need to get professional advice before structuring anything related to offshore.
