Version 4 - www.pastetrader.com <-- being live-coded on twitch.tv/casey_works
There are loads of crypto tools out there. Paste Trader is different in that there's no login, no API keys, no-PII required, no usernames and no manually inputting your trades one by one.
It takes in deposit, withdrawal & trade activity as CSV exported from one of 78 supported exchanges. Paste/import those files into the app and you're in.
