Arbitrage analysis:
The current Bitcoins prices has gap in different country/region.

Europe -> China (+10%) -> South Korea (+20%) -> South Africa (+30%)
There is a huge space for arbitrage.

Arbitrage key points:
1. Price gap
2. Transaction cycle

And the second point is more important than the first one, the second point depends on the speed of money out.
For South Korea / South Africa, there is a strict foreign exchange management system.

China also has a foreign exchange management system, but Hong Kong China is a well-known financial free port.
Therefore, Europe and the United States -> China, is a good way to arbitrage.

About me:
Chinese, have a bank account in Hong Kong.
Hope to find the cooperation between Europe/U.S.

If you are interested, we can video chat, or meet.
