Hi, I just created this tool to help track my profit and loss on my coin investments.
I need lots of beta testers to help me iron out any wrinkles and also determine important features to include.
The website is
MyCoinTrades.comIt currently works with Coinbase since that is where I started trading but I am now looking at integrating other exchanges.
Check it out and please let me know if useful for you.
