Not every investment pays out. Some relationships don't pay off. Some investment into the various things don't pay off. And even the investment into the coins, stocks, gold don't pay off. A lot of those things have some sort of unknown variables on them. And we have to take risk in order to make meaning out of them. Not all investment pays off, so think before you invest into anything and anyone wisely. Make sure to take risk by calculating the opportunity. Never invest into wrong things.
