Since you can't deposit/withdraw fiat on Bitfinex -How does it control the price

[adaseb]

I am just wondering why Bitfinex is the BTC price leader compared to the other exchanges when its the only exchange where you can't deposit/withdraw fiat.

Its seems the exchange is zero-sum. So if some whale wants to buy 1000 BTC, he needs to deposit some BTC he already owns and buy it on margin?

Or does this exchange simply follow the other Chinese and smaller exchanges ?

Where does it say you can't withdraw or deposit fiat?

It's the only big exchange where you don't need verification if you're only depositing or withdrawing coins as far as I know so perhaps you're getting it mixed up.

I think the OP confused btc-e with bitfinex.

As 1Referee posted above both BTC-E and Bitfinex allows deposits and withdrawals.

I don't understand what you mean by "How does it control the price"?
An exchange cannot control the Bitcoin price. Its the traders on the exchange who controls the buy/sell price.
