Something like "weighted avg. paid" for every coin would be great, along with %profit shown.
Like, I bought 10k of some crap coin for 0.0000001, then 5k more for 0.00001 when it was pumped, so my weighted avg paid is
(10000 * 0.0000001 + 5000 * 0.00001) 15000 = 0.0000034 BTC
so the acquisition value was
10000 * 0.0000001 + 5000 * 0.00001 = 0.051 BTC
or
15000 * 0.0000034 = 0.051 BTC
now the coin was dumped and it's sitting at 0.00000005, therefore my holdings have a value of
15000 * 0.00000005 = 0.00075000 BTC
so my ROI is
(0.00075000 - 0.051) 0.051 * 100 = -98.53%
which means i'm fucked -.-"
bonus points for a list of buys/sells for each coin where you can enter your trades so you don't have to manually compute the weighted average price paid.
