I mined RVN long before it was available on an exchange so there is no historical value to calculate their value at the time I acquired them. I've got hundreds of transactions... apparently I was using a pool that paid out every 10mins for a good portion of this time period. When I try to highlight multiple transactions and edit asset value it seems to assign the same value to all the highlighted entries. Since all these entries have varying values for the amount mined this ends up being inaccurate for me. Is there a way for me to assign a value of say, 100satoshi per RVN and let it calculate the RVN's USD value based on the known BTC price during on my transactions timestamp?
