Land is better than Bitcoin.

Bitcoin, gold, stocks and shares and property are all artificial constructs to a greater or lesser degree.

N.B. Gold value is an artificial construct, not gold itself!

Land is not.

But land is not fungible and is stable in value.

Also, land ownership requires trust and permissions, so has traditional disadvantages.

As for what to sell Bitcoin for, nothing in the foreseeable future. But plenty in the unforeseeable future.
