Don't you think Bitcoin can easily manipulate and below $1000 is still possible?
No, I don't think that is possible nobody can manipulate Bitcoin when it comes to its price in the market. Even whales can't do such a thing. Traders are smart enough to see if there is a manipulation going on in their exchange.
manipulation is a matter of degrees. it can go from full control of the market and the price down to only having slight influence over a short period of time. with that said manipulation exists in every market in the whole world without an exception. so saying it doesn't exist in bitcoin is a naive statement.
