gold - silver ratio long term

Updated
Beginning of 2020 the ratio was at 126, which means it took 126 oz of silver to buy one oz of gold. A few months ago we had been at a ratio of 62. That means silver had almost doubled it's value regarding gold. We are at 69 currently, so if I would have metal and I expect the ratio to go up again this would be the time where I should exchange my silver for gold.
However, I do have neither so it makes more sense to take fiat to buy gold if I expect the rate to go up again and at a later point, when I would get more silver oz for 1 gold oz I should exchange one metal for the other. Can someone confirm this?
Note
If, on the other hand, I would expect the trend to continue and the ratio goes further down, it would mean I we would be better of buying silver with fiat.
