Some rules about investing that I learnt in my short years playing with money.
1. Never count your chicks before they hatch. - You know you made money once you are out of the deal and have done the math. Looking at prices for a stock/product you are still holding doesn't mean that you will get the same on your exit day.
2. Know your place on the table - Minority shareholder means you are hanging on the tailcoats of other decision makers. If they choose to reinvest returns or divest the business, too bad for you.
3. Forget the marketing - What you see is what they want you to see. learn the scuttlebutt technique for any investment worth a substantial sum. If I don't understand how you are making money, then am a fool to be investing.
4. I know my limits - I know at what point I am willing to count an investment/deal over and count my losses. Beyond that limit, it will stress me and I don't need that.

As far a Cytonn is concerned, some people who put in a million, just couldn't stomach losing a million. Some people knew nobody in the organisation yet they believed and based their decision on what some sales staff was coached to tell them. Some people didn't understand the exit points or the lack of them.
Either way, hio ni funzo.
