The dashboard shows an incorrect total value, because some tokens are listed with value 0 due to missing prices.
It would be a good idea if we were able to manually capture prices for a certain coin at a certain date.
For example, I would capture the prices manually once per month and could get a pretty good estimate of the current portfolio value and allocations.
Why manual capture? Because, I believe it is impossible to stay up to date with all coins, LP tokens, etc.
