It's not really a scam to move your cash into non liquid assets for financial security. How you got there could be a product of a scam but (going off of a previous comment I made a few days ago about how they buy assets and hold their money in those) typically, after you have a certain amount of money, one can only figure boredom kicks in and that in-turn, would most likely create a sense of frivolous spending or seeing what you can hold in forever items with absurd values.
Paintings, Collectable Cars, Mid-Century Clothing, Collectable Foods (ikr), Historical Properties (that sometimes get sold and then they re-coup losses through making the historical property profitable....sigh,,,, creating a historical society with the goal of recouping losses). .......
