Well I am not investing at all, though I do follow the numbers, and have a knack for seeing patterns long before most catch on to them. And I learned the lesson of nominal gains over anticipated values back in 2008 when I got into the precious metals community. "Hodl" is just a recent take on the old stacker philosophy. If you're trying to accumulate something, don't worry about its value, worry about its weight.
That said, if you never worry about its value, you will find yourself buying at bad times. Best to buy cheap if possible, which is why I do find it important to follow these data and trends.
