Difference between forex margin trading and stock trading

Some investors target the relative value of foreign currencies between two nations in the back of business trend and outlook in the forex margin trading, and others targets the prospect of the companies in the stock trading. The currency does not disappear as long as the relevant country goes alive, but the stocks may become just a paper scrap when the company goes bankrupt. Needless to say, forex trading is more stable to invest from a liquidity viewpoint.
