Anything suggestion all? my preferred trading is USD/ETH or USD/BTC
Hope the suggestion is the one you had experience with
I think you'll like Kraken. They have ETH/USD and USD/BTC which are the pairs that you trade and they have relatively good customer support and low deposit/exchange fees compared to the rest. It's a smooth experience trading with them. I think they do have a analysis tool for your trade profit/loss but you need to check that yourself.
If you like Bitstamp then just stick to it and download the blockfolio app.
In there you can enter buy and sell orders and it'll calculate your total portfolio worth as well as a tracking of your performance.
