I'd just settle for the option to be added to Quicken to increase the number of decimal places to 8 to accommodate cryptocurrency share amounts and prices.
Thank you for taking the time to visit the Community to post your question, although I apologize that this feature isn't currently offered.
I have moved your post to the ongoing Idea thread to add the ability to track Cryptocurriencies in Quicken.
This Idea is under consideration and being reviewed by the development team, I do not have an ETA to provide when or if this will be implemented. Any changes or updates will be posted on this thread.
