Ok, i got your point.
There are no such option, its a little tricky since blackfolio is not a full accounting fortfolio.
You have do it manual if you want to shown your btc
When you sell your altcoin, your alt qty will reduce and you gain btc in return
as blockfolio didnt directly count the btc that you gain for that transaction, you have to input (buy) btc manually against fiat
I don't have BTC - I sold my altcoins for
USDT.
I guess the bottom line is that Blockfolio can't handle selling alt coins for USDT or USD and has no way of dealing with my transactions.
In my case then, it seems Blockfolio is only useful to keep track of market value on cryptocurrency.
Okay I understand what you're getting at.
I believe it should be possible to reflect this in Blockfolio in some fashion, because if the trading pair exists, Blockfolio should have it listed.
I just tried it with Neo, since I know NEO/USDT is a trading pair on Bittrex, but Blockfolio doesn't list it as an available exchange for NEO/USD.
But at least I can find the pair and have it reflect my transaction in USD (although it's at the wrong exchange, it's an indication). That's the best I can come up with at the moment. Hope this helps somewhat!
