I signup last day on kraken because of ICN but I didnt transfer my coin. I find it difficult to trade, as I am still familiarizing with it. I find it difficult because the graph menu is on different menu from account.Meaning you have to open two window to monitor, I hope they incorporate it in one page like the most exchanges where you can put your order,view the Order book,graph etc.
This is just my experience about Kraken and their margin trading are so complicated if comparing with the another exchange are the volume is below then Kraken I just think there is better than this one. that's so complicated for me and about for depositing icn tokens are get some trouble.
