Because I think there is no end to forex trading because now days people do work through the internet within the country or beyond so that currency exchange will always increase in time and if other closed trading options will open under forex trading.
This business has an effect on the country's currency value, I think this business will not be so easy to end, even if there will be problems with the global internet, but I am sure this business will still work even just a few client jobs in this business.
