For me, it has been already nearly 6 hours and 6h30 that I sent from GDAX 0.04 and 0.01 BTC to HitBtc , Bittrex and Jaxx...still nothing !!
I wrote already to GDax support after 2h30 and 3 hours but still no answer...
What else can I do? Just wait I guess ...? How many more hours can it last ?
GDAX send the currency for free, I guess they pay the network fees by themselves?
