Blockfolio shows higher percent gains in BTC then in USD?

[shoxx187]

Hi Guys,

I just joined this forum so please be nice and kind

To my confusion I recently noticed some strange calculation inside my blockfolio app. When I switch between BTC and USD view by tapping on the dollar amount, the percent gain of my listed Coins differs greatly:

You can see what I mean in the last entry: I bought 14 NEO for 35,81$, which gives me a loss of 7,24% in dollar. But the same entry gives me a +5,85% gain when viewed in BTC.

Can someone please explain what I am missing?

Thanks in advance!
