I officially moved my trading funds to Kraken. 
fees are lower there?bitfinex has a bit lower fees. they are seperated in 'maker fees 0.1%' and 'taker fees 0.2%' kraken has a fixed fee of 0.26% for people who's volume is less than $10K in value. op isn't going to get cheeper fees.
But kraken is REALLY reliable. I trust them a lot more than I trust finex, ohh but the volume is lower so it might not work out very well for day traders.
