Estimated Value and Profit percentage calculation is wierd when assets already exist in spot wallet

Describe your environment

Operating system: Windows 10
Python Version: 3.9.7
CCXT version: 3.0.43
Freqtrade Version: freqtrade docker-2023.4.dev-19e112f3

Describe the problem:

Hi, So yesterday I first time started a bot on live binance. In my Telegram I can see when I checked the "/balance" right after startup, since I already had some coins like BAT and UFT lying around, it would see 211 BUSD as "Starting capital" and then at the end of the message added the other assets together for the estimated value of ~320.

So far so good, but after the first trade was done and it made 1.8 BUSD in that trade from a 1.2% profit trade, it then took the Starting capital BUSD of 211 and compared that to the new estimated value, showing an astounding 51.98% profit. Which doesn't make sense.

Wouldn't it be better for this scenario to use the estimated value at the start as the starting capital, if that is what we are comparing future values with?

I mean i'd love to have 52% profit, but i'd prefer that to be a real number :D

Steps to reproduce:

Start bot on live with different coins already in wallet
ask for balance
wait for one trade
ask for balance again

Observed Results:

Wrong profit percentage
