Although I’m in the UK I tend to look at and consider all prices in USD. For tax purposes, I need to use GBP.
I just noticed my base currency in Koinly was set to USD so I changed it to GBD which seems to have worked fine. My question is, if I flip the base currency back and forth between GBP and USD, will there be rounding errors each time? I’m hoping that at the lowest level all currency is held in (say) USD and just converted to the base currency when necessary.
