I return the question : Why do you think every rich people from the West are trying to get their money out of their own country ?
Because:
- governments can change and cannot be trusted
- the legal system cannot be trusted
- they want to pay 0 (or very low) taxes on the money
- the money is from illegal activities and is increasingly difficult to hide
Honestly I think this is one of the 2 main reasons why bitcoin could increase in value (by a factor 10 to 10,000).
Why? Because when those countries agree that they exchange all personal bank data between each-other and on top of that agree that bank transfers from non-member countries will be taxed xx% only bitcoin, gold and cash will remain to get your money back. Since gold and cash are difficult to transport bitcoin will profit enormously.
The second reason is a default of a big European country (like Italy, Spain or better France). Fear of a haircut tax will drive many into bitcoin.
