If you want to know what a real bubble is, then look into Ethereum. Bitcoin's price was overbought, but not to the extent of it being a bubble. Bitcoin has been experiencing a massive amount of growth from all over the world, and that's all legit growth. Also take into consideration that there has been a burst of good news, all in a short period of time, wich has lead to the price being overbought by panic buyers and speculators/gamblers. Overbought is not the same as bubble.
I want to believe you. But there are no facts and numbers backing up the claim that "legit growth" really is happening in Bitcoin. Everyone is saying "it's Japan!" but they do not have the facts as well. So where is this legit growth coming from? The dark markets? That is more believable than the "it's Japan!" everyone keeps shouting about.
