Fettercairn 40 year old

[tometoyou]

Hi would like some advice from some more knowledgeable whiskey lovers.

I have recently received a bottle of fettercairn 40 year old and wanted some advice on it. I have two options really I could sell it now or keep it for 10-20 years to keep for special occasions or sell in the future.

With the whisky is it now at its peak or will it improve with age? Is it likely to increase in value or is £700-750 the most likely value?

Thanks
