The number one automatic tax calculation is CryptoInsight (https://www.trackr.im/), they're coming up with a new version that automatically synchronize your exchange/s accounts and trading, according to your country of origin (for tax purposes).

FYI - they are using TKR token for their project - https://coinmarketcap.com/currencies/trackr/

Have taken a quick look at it, still seems in very early stage. Keep up the good work! Is the platform releasing soon?

BTW whats the purpose of having your own token? What is it used for?
