Bitfinex has not been my "go to" exchange. Nevertheless, I've always understood that the market can be maniplulated.. .just how much to the extent that it really affects me. But here's the thing...my dealings with Bitcoin really is only in regards to when i sell other coins. I'm more interested in many alt coins than bitcoin--the crypto currency. I think Bitcoin--the king of cryptos-- is fine but i really just use it in regards to tansfers to buy and sell other coins. A lot of problems we face as investors wont go away until many people come out of that bitcoin tunnel vision.
