what would you advise folk not to buy !!!!!!!

[BDG]

It is only an asset to you so long as you keep it secret (then what is the point of having it, unless for a time of law and order to come back?) or have the means to defend it that cost less than the value to asset appreciates by.

Otherwise, it is nothing more than a liability. We can look to the archaeological records of the Dark Ages for that - how many hordes of gold and other precious things were buried for hope of recovery in a better day for a person or their descendants?

Unless you can break it down into small parts to trade with, and hope it is tradable - perhaps holding onto rings that may be used as wedding rings may be a commodity of gold that you could trade that people may want in a society where common law has no weight?
