I have a reconnaissance/acquisition mindset...I drink first, but if I find something I really like I'll buy another bottle and put it away. I'm about 9 years in now at 45 years of age, and at some years later point will start cracking the bottles I've saved. I only have 15 or so bottles so far, so I'm not collecting at a rapid rate at all...maybe one or two a year.
My intention is not to hoard against future value, but rather to get a second chance at something really good later, and to trigger memories of good times gone by. There's nothing like smell and taste to take you back in time, and I should have a lovely stockpile of bottled memories to get through a few years from now.
And of course it keeps rolling...find a good'un, put another away. I hope my daughter drinks whisky one day
