How much money would I have had now if I would have known in the year 2000 what I know now? Sometimes I think back to that period 10 years ago when I did not have a system yet to warn me for when stock markets are starting to fall and continue to fall.

Did you invest already in the stock market in the years 1999 and 2000? If you started to invest in the market after that period, you have probably experienced only one market meltdown: the one in 2008. When you started to invest in the stock market before the year 2000, you have seen two meltdowns.
