Stock market offers an opportunity to create wealth over long period and also liquidity on short term. While the probability of winning is 50% , the return over risk is worthwhile compared to many other financial instruments.
The Money market is a fascinating world which can survive apparently without food and water. All they need is money to eat , drink, sleep and dream.
