After reading this snippet on today Bloomberg newsletter, I remember about a special Fintech I found some years ago:
Whisky, music and the great outdoors are among hot alternative assets in 2021. To invest in your health, consider the $1,495 LiteBoxer, the “Peloton of Boxing.”

What do you think about investing in a very liquid investment, Scotch whisky? 
There is a British Fintech launched in 2015, WhiskyInvestDirect, a Scotch whiskey marketplace that allows investing in raw Scotch whisky (grain and malt) from distilleries that ages in casks, and after that the investors could sell it to the major whiskey brands or to other investors:
From the Bloomberg article:
Why now: Spurred by rising demand from Asian investors, the value of rare whisky has soared 564% in the last decade, and the asset has outperformed not only fine wine but every other luxury asset, according to the Knight Frank 2020 Wealth Report. Knight Frank’s data shows rare whisky soaring despite the volatility in markets in recent years.
Risks: Casks, which are stored in warehouses, can leak and break down, degrading their contents so much that the liquid no longer qualifies as Scotch. You can insure casks, but that won’t make the whisky you’ve waited for taste any better.
Note: Scotch Whisky and other real assets are alternative investments that share in common, the fact they are iliquid investments.
