A new ATH might happen in the next 5 years.
5 years is just way too long IMO, Bitcoin is now almost a decade old and still having a hard time breaking into the mainstream, what people don't get is that the longer Bitcoin drags in penny stock territory the more it becomes viewed as a fad. When you consider how fast companies like Google, FB or Twitter grew it makes Bitcoin look like a stunted child, you can only beat a dead horse so long.
Whales better try and move this thing soon or risk crypto fading into memory.
