It would be nice to get a longer timeline for the portfolio/token amount up to an year in firefly.

Motivation

Some thoughts if we pick this up:

• It would be nice to have this dynamic based on the data available. i.e. if we have less that 1 month data don't show the 1 year in drop down etc.
• Add additional options 3 months, and all time.
