Help anyone please? I need to know what are slumps and what are rallies.
Seriously? Slumps are price decreases, rallies are price increases. They're quite literal in this context.
On to the topic at hand, I do agree that past precedents don't necessarily apply to Bitcoin. It continues to break expectations and sharp drops are usually met with all time highs with lots of people waiting for an opportunity to buy the dip. I also wouldn't compare it to the dotcom bubble. That only lasted for four years, and the amount of money poured in was more than 10x our current market cap. Bitcoin is proving to be far more sustainable.
Bitcoin is the first of its kind so its growth can't really be conclusively compared with anything else's.
