I think this is a really interesting idea. I actually wrote a little CLI to help compile the coins and exchanges.

I'm having issues with the wallet syncing. It's stuck "No block source available..."

I'm curious on two items.

1. How are realized and unrealized gains calculated? I'm a bit confused and think it must have to so with FIFO or something. In particular coins I use to purchase alt coins have some results that confuse me. IE. I hold BTC and also buy it to purchase alts and the realized gain/loss is very surprising to me.

2. It looks like everything gets paired against USD so there must be a historical price database that is being referenced, is this correct? If so, is this something that is publicly available?
