Anybody ever think of OTC stocks each as little mini bubbles? They say a "bubble" is exuberant highs, goes higher than people think is possible, for longer than any short can remain solvent, but all come crashing back down to earth, usually doing more economic harm than necessary. If you look at a chart of the Tulip bubble, Bitcoin, 2000 era tech -- They all look like most longer term OTC stocks that had a run. That's because they're ALL SHIT, but also because that's simply how momentum in general DIES.
People will always argue, "YeaAH but XYZ went to $29 so suck on that, idiot!" and completely ignore that the statistics on that happening is EXTREMELY RARE and there are clues you can look for when identifying a runner.
Here's a long term BITCOIN chart. The similarities to any of your OTC runners should be obvious.
So when people say "Looks like a pump and dump!" Well, yeah, thats' because pump and dumps are BUBBLES, too. But if you look at a chart like that and all you can think of are boiler rooms then you probably need to get out more.
So is bitcoin getting ready to run from down here? Sure looks like a potential bottom, and the crowd thinks bitcoin is DONE FOR. So might be worth a shot. $GBTC
