i m gdax user
the goods
your usd eur etc fiat funds in coinbase account is insured up to $250k
https://support.gdax.com/customer/en/portal/articles/2689803-how-deposits-are-insured-on-gdax?b_id=13522coinbase one the safest wallet i guess they keep over %90 of funds in cold wallet
app is good and stable
transfer between coinbase gdax wallets are free and instant
the cons
moving your money to coinbase is hassle
even for us residents which they can see all your infos on credit bureau system added bank acc added us pass state driver license bank statements
and it is been more than 18 months still my coinbase deposit to coinbase $50 a day so the best way buy your coins out side and deposit to coinbase for trade at exchange i bought from local coin and transfer here
GDAX
good stable web based exchange
no stop loss no take profit because of limit web browser it is laggy in volatility times forget about to be maker and avoid their fees
when position is open you can see your unrealized P/L but when position closed no way to see P/L
leverage is good up to 3x and free for now but it is not fixed software keep change your limits
when goes up or down usually your buy/sell limits cutted to almost your total fund
chart is useless so you have to track some other charts but than you lose correlation between other charts and gdax web chart
between coins like ltc/btc no leverage
when falling shorting no leverage or very very minor leverage for example 1.2x
same like gemini i think they do have dealing desk bots
when you try to be maker and avoid fees as soon as you hit buy or sale in milliseconds price moves and you'll see minor buy or sell order in front of you of course this is mostly will be opposite direction of trend and you are missing a moving train (same at gemini)
when spread is $0.01 it is okey but when little volatility starts forget about just hit market price and some time thats come with worst price that you seeing on screen.
authy 2fa is good but even if you remove from phone and reinstal you are stuck need to email support team they will answer in at least 48h and you have another 24h to authy keep sent you sms that auty 2fa is resetting
this is time loss please gdax allow to remove authy 2fa i was happy with regular sms 2fa now i can't go back to sms
you cant see your actual balance without closing your positions you see last positions + or - in red green buying power usd balance but no how much money do i have you have to use calculator to find out
basicly for quick trader they are not so good but for little longer trade awsome you can keep up to 3x leverage for 28 days.
i will edit this post when remember some other details.
