I attempted googling this, however I get a litany of the reason why it will not work as an alternative. This appears trivial to me:

• If I’ve 1 BTC in my pockets when 1 BTC = 100 USD
• Then I transfer 1 BTC into my pockets on the identical day
• Then the subsequent day the worth jumps to 1 BTC = 200 USD

To me, in that 24 hour interval, I’ve made a revenue of 100% as a result of my portfolio went from 2 BTC valued at $200 to 2 BTC valued at $400. However Ledger Nano app says I’ve made a revenue of 400% as a result of I went from 1 BTC valued at $100 to 2 BTC valued at $400.

Is there an app or web site that may calculate the precise appreciation of my coin primarily based on the alternate charge on the time of buy? As a result of proper now, I’m manually making a ledger in Excel like a peasant.
