I also think that when it comes to trading cryptocurrency if you are using these two platforms then their exchange fees can be quite high compared to your traditional cryptocurrency exchanges. So if you are looking in the future to try and trade between different coins and see how you can make a profit from that I suggest that you look at investing your time into a proper cryptocurrency exchange. The one that I use has a 0.2% fee on each of the transactions.Thank you very much for sharing your experience. I am not investing or trading crypto currency yet, I only use coinbase as a wallet. I hold my coins until I have enough to cash out. I also have a blockchain wallet but do not use it too often. having said that I might consider using it if I am ready to invest or trade.
