I do not understand why all you guys call this bubble? If you cannot figure out the value of the BTC, then how can you call it a bubble?
They are repeating it after some of those old farts from Wall Street who made some decent deals before the first white paper was published.
There are much bigger and dangerous bubbles currently bro, are you aware of that? just check USA or Japan debt, those are like close to 200 Trillions and growing every second we talk!!! Bitcoin in comparison it's a still a tiny cute small baby, keep that in mind, to the moon! 
Exactly. Some people seem to think they will buy cryptos, wait for profit, exit to fiat and it will all be fine at that point. No, it won't. You are exchanging independent, but scarcely accepted currency for another one that is still vulnerable, centralized, but widely accepted. You're exchanging one token into another, fiat is by no means better or safer. The main difference is that with crypto you are on your own. Nobody is making promises to you or holding your hand, giving you a false sense of security.
