I appreciate straightforward advice to avoid illegal activities. Your idea of starting business outside of France perhaps in Dubai and using Bitcoin as initial funds is good because countries like UAE have no personal income or capital gains tax which means more profit for owner. This strategy of setting up business and receiving profits as salary other than being hit with large capital gains taxes is clever way to save money on taxes showing why it is so important to understand different countries tax rules before making big financial moves. It is bold plan that could be very rewarding if handled carefully and legally.
