However, while a bubble usually explodes once catastrophically, and never reaches popularity again, bitcoin is not like that. And Bitcoin never reached anything close to zero, whereas bubbles are usually identified in hindsight (so even if Bitcoin is one, we can't know that yet). And Bitcoin value being zero doesn't make any sense to me.
Just like the STOCK MARKET BUBBLES POPPED, and then never went into bubble territory or gained popularity again

Just like the HOUSING BUBBLE popped, and never reappeared

You are just wrong in your statement " never reaches popularity again "....
Now here is the scary part

Bitcoin is backed by NOTHING, it is not a house, it is not a company that can produce things, it is just a speculative asset, and its only value is that someone else will by it hoping that it is going to go higher. The moment that market psychology changes, bitcoin will go to near zero...
