Neither. They serve different purposes - GDAX is predominantly for exchanging fiat in to BTC/ETH/LTC, where as Bittrex is for exchanging BTC/ETH/USDT in to altcoins. However, GDAX is part of Coinbase, who are pretty shady in terms of insider trading and the BitcoinTrash scam, and Binance is generally seen as the best altcoin exchange.

[JamescrypTrader]

My reference will go for bittrex. Just because it deals with all about cryptos. so you are supposed to be in the crypto industry.

Thank you guys for sharing your prespectives. Does binance accept a Crypto-FIAT exchange?

Not yet, but they are planning to support fiat in the future.

If you are a newbie, Coinbase/GDAX are probably still the easiest to use fiat exchange - I just dislike them because of their business practices. Other popular fiat exchanges include Bitfinex,  Kraken and Bitstamp.

Really depends on where you live and whether or not you plan on filing you're taxes on crypto-crypto transactions, GDAX is good for buying bitcoin and some other alts for fiat, bittrex is more of an all around altcoin exchange.

Binance is probably best right now but there a lot of coins you can get on bittrex that you cannot get on binance.

[blu.storm]

first my favorite was bittrex because it have many altcoin to be trade but now i prefer binance that at the moment is the best in my opinion

[allen67]

Both of them have some notable points. But my preference is for bittrex. Because it deals with almost all the cryptos. And it is also easy to handle.

[jawatulen]

Which of these two is the best exchange?

in my opinion at this moemnt, bittrex is better than others cryptocurrency exchange
and huge trading volume in bittrex is the main causes

[Devanomrz]

Both are good
But if you want to play altcoins
Bittrex have more than GDAX
And i think bittrex is number one on altcoins

[bellamente]

Bittrex is a more popular exchange in Asia, the CIS and Europe. Then the Gdax exchange is designed for the US and part of Western Europe.

For me, Bittrex is a more reliable exchange

[yura888]

Which of these two is the best exchange?

Personally, for me, the favorite is Bitrex. He's just more suitable for me. But I think Gdax is also a very good exchange

[Tosin12]

Really I haven't heard about Gdax before but I just checked and I could see it's different from Bitrex in terms of what they are useful for, Gdax is an exchange for Fiat to digital currency while Bitrex is exchange for digital currency to fiat So we cannot compare them

[raven.tiu17]

I would choose Bittrex here even though GDAX is popular too in Western Countries. But if you going to pick a good quality altcoins then Bittrex is the choice for altcoin community. Try to compare this exchanges and give us info.

[salinaangel]

Not one or the other. They fill distinctive needs - GDAX is overwhelmingly to exchange fiat in to bitcoin, eth or ltc .Whereas Bittrex is for trading btc, eth or usdt in to altcoin. Be that as it may, GDAX is a piece of coin base, which are quite shady regarding insider exchanging and the bitcoin, Binance is for the most part observed as the best altcoin trade. It is up to you now.

[Dreamchaser21]

The volume of coin that is being traded with Bittrex is much higher compare to Gdax and Bittrex is now a trusted exchange which you can find a lot more secure compare to a new exchange. It's easy to trade with Bittrex though the fees is quiet high but I still go with this exchange.

[chainguru12]

Which of these two is the best exchange?

Bittrex is more better in terms of technical support and quick trading

[VanDeinsberg12]

Which of these two is the best exchange?

Gdax is bitcoin exchange site and bittrex is an altcoin exchange site. GDAX is much better rather than bittrex. As an altcoin exchange site and bittrex has been loosing a lot of the trust from the traders.
The reputation of the bittrex exchange site has getting a lot of decrease since there was a lot of problems between the bittrex and its users.

[altsMlk]

Each exchanger has different approaches. We can use both or specific one as our needs and choice. Mine is bittrex.  Coz Im a crypto trader. I do not involve much with fiat currencies.

[dumiya]

It is not to reasonable compare a fiat/crypto exchange with an altcoins exchange. However, I would choose Bittrex over GDAX as the answer for OP's question as it has lot of trading pairs. Another reason is GDAX operates in few countries at the moment because they should have the legal authority to do so (Involving fiat means they need to comply with the laws and regulations). GDAX doesn't operate in my country too. In other hand Bittrex is just an altcoins exchange which means no fiat involved. They operate in most of countries.

If I give a general answer, I would choose Binance as my favorite altcoins exchange and Bitstamp as the fiat/crypto exchange.

[googs84]

Which of these two is the best exchange?

I consider bittrex only for one reason and that is the volume that gets driven into the exchange. Its huge so you dont have to wait for your order get executed at all times. You just place the bid and mostly it gets filled as someone will always be there to buy or sell at the same rate as you are making the trade. So that is why first preference to the Bittrex only. However recently I have started using the Binance also, just adding up that as it is getting even better than these two exchanges so if you wanna get started with the crypto then thats the best place to get started with.
