I'm sorry you decided to conduct algorithmic trading of digital assets on multiple exchanges without ever considering taxes. But services such as those linked by the OP (and others like bitcoin.tax) automatically import trades from all major exchanges and calculate the most advantageous method to minimize taxes.

I was doing various cryptocurrency mining in 2011 and trading in 2012, long before bitcoin.tax existed. Many of the exchanges I used have since shut down.
