That's exactly why you short, i'll explain.
The popular belief is that the run from 300$ usd to 20k, a.k.a the bull run of 2017 was because the sentiment was of greed. It's exactly the opposite: the bullrun was happening when a LOT of people (and i mean a lot of people) but specially the media, saying i was the impending end of crypto and of bitcoin, meaning: everybody was fearful that the run up was signaling impeding doom.
Now everybody is greedy and the media is greedy that the bull is back, that this is the run, this is the return of jesus fucking christ, the new paradigm of bitcoin and crypto reaching new heights.
Tl;dr: short the golden bull run fable
Other thing: i cash out on a brazilian exchange, i'm from a third world nigger faggot country called brazil.
The exchange i use to cash out during the bull run had enormous vollume. In this supposed start of the bull run the volume there is mediocre at best. (Proof that the exchange does not fake it's volumes)
During the 2017 bull i can say with certainty that the exchanges there where solid, because they only operate with bitcoin, bitcoin abc (cash at the time) and ethereum. There's no alt market there.
Now, in this suposed bull there's an exchange here called negocie coins that as of today is the second exchange in the rank for volume. GLOBALLY. That's absurd, the market here for crypto is pretty much low to non existant at the moment.
If we were in a true bull this nigger country would have volume across the board.
Money is made by liquidating dumb people. You must take from someone who made a wrong move to be rich. THAT IS A FUNDAMENTAL TRUTH.
Big players will make money crashing hopes and dreams of those who think we are trully in a bull market. And that's clearly not a bull market but a manipulated one.
