It worked for you in the past
The pot oft sent to the well is broken at last. In other words, just because you made a successful investment in the past, doesn’t mean it will work out again in the future. It doesn’t work that way in the investment world. Even the Securities and Exchange Commission says so and recommends investors to consider that “past performance is not a reliable indicator of future performance.”
If you simply cannot resist an investment that turned out to be profitable for you before, do some research to see its current situation and then act accordingly.
