Transaction values in egld and dollars at the time they were made

[J. G.]

Hello! I don't know if this feedback has been reported or not but there's something not convenient on Maiar. When there's a transaction done, the equivalent price in dollars is displayed (in the "Activity" part). However this information keeps changing-since the egld price in dollars changes as well. 

I think it's better to have this value as being a fix value, otherwise doing accounting is impossible.

I support this feature request.

This would help me immensely with doing my taxes, when it comes to staking :)
