What is the current history module storing since we replaced all historic data with Hasura actions? Cause I think it might be easier to move the historic token storage inside the pricefeed module itself so one module does everything there's needed rather than splitting into another module (which needs to be enabled)

[MonikaCat]

Currently history module is storing historical price data only. Sure, I moved it inside pricefeed module as per you suggestion 👍🏻

I removed the part that forced all the prices to have LastUpdated set to time.Now() as I think it wasn't correct. @MonikaCat Was there a specific reason that one was there?

[MonikaCat]

@RiccardoM Last Updated timestamp is fetched from the coingecko and it reflects the time when the price was last updated. We need the exact value at exact time every 1 hour to plot the graph. If price hasn't change within that 1 hour, the returned timestamp will be the same as one hour ago and it will not be stored in db as it will be a duplicated value. So that's why we should pass the current timestamp rather than the timestamp fetched from coingecko.

Ok thanks, added back with a comment
