Let me know guys which countries are having 0% tax like Portugal and it should be easy to open bank account in that country. This topic will be in demand as many Indians are finding it so difficult to pay up 30% tax from their income, while most other countries like Thailand and USA have 15% tax.
There is a huge difference between receiving money in a bank account and paying taxes.
As @avikz mentioned, you will still have to pay tax where you're located, for example since I'm in the EU I could open a bank account in Germany in minutes, sell some coins on Bitstamp and have the cash wired there, do you think I will just get away with it and I won't have to pay taxes in my own country?
Everyone in the U would be opening German and Portuguese bank accounts and nobody would be paying a dime in taxes, but taxes are not paid on money transfers, they are paid
on income! So unless you manage to set up a business there, run that business under Portugal laws, manage somehow to slip your coins in the assets, and then only use that business as a cover for your personal purchases in theta country while not getting in trouble with the IRS, you won't be avoiding anything. But most likely you will face jail time for all this.
Oh, and one more thing, it doesn't matter even you sell your coins to some stranger f2f, it's the same thing, you're covering the tracks of the exchanging, you're not hiding your money. Off-shore accounts only work because nobody is stupid enough to withdraw money from those to their own bank account!
