Is the Cost of a PoS Attack Dynamic?

Yes, the cost of a PoS attack is highly dynamic. It is directly tied to the market price of the cryptocurrency, as an attacker must acquire 51% of the staked supply.

If the coin's price increases, the attack cost increases. Furthermore, the attacker's actions would cause the price to crash, making the attack economically self-destructive.
