RM100,000 isn't much these days to invest. Any fast money is risky, stock market is risky if the money is hard earned. Invest in good return real estate needs more than RM100,000. I would consider to loan money from bank if possible and invest RM50,000 in business. Work the hardest possible than other ppl, have good attiutude, focus on what you doing, and be nice to ppl, I am sure your investment will double in no time and it is long term plan. Any business can expand and well known, just depend on how you manage it.
