It has to do with the dollar exchange rate and also with you having bought this currency in exchange for another, and this other one having appreciated more than the one you have now.

Hello everybody!
There is something that is leaving me intrigued.
On 10/12 the average price of two of my cryptos was one. And today on 3/1 the average price is higher, even though I didn't invest in any of them!
Can anyone explain to me what could have happened or if this is normal for the average price to increase without having made any purchases?
Thank you very much
