Yeah yeah I get all that. My salient point is simply (with a large dose of hindsight) I wish I'd bought back in 2017 and sold around 2021 when the price significantly increased, regardless of whether or not I thought the price was going to continue upwards.You don't know the top of the graph, or the bottom, until after it's too late.
When you invest in a business, you (should) have some idea of how well it's run, is it profitable, is it sustainable, is it based in an honest country, is it run by a crook, is it growing, and enough to start taking a real view of its future worth.
