I'm looking for a google spreadsheet to keep track of my coins. I found few online that are quite good but each one is missing something that I want to use.
I need to have multiple currencies  (eg. USD and GBP, USD and EUR, etc), the price of the coins updated (using API or something), my transaction with the actual price I paid + gain and loss column. A very good surplus would be some pie chart with % of the coins owned, etc.

I fund at least 3 good google spreadsheet that I could use, but each of them is missing one of my needed features while having the others. I'm not so skilled to do a new one by myself nor mix and match the existing.
Can anyone link to some spreadsheet?
