Nitpick: BTC can be worth effectively less than $0 if you buy some then the price drops. But in a Pascalian scenario, that’s a rounding error.
No, that would mean that you have an investment loss. Bitcoin is still worth $X each, whatever the new market price is. When you buy something and it goes down in value, its not worth less than $0, its just worth less than you paid for it.
There are some events where bitcoins might form a negative value. For example if somebody stole a big amont of hardware illegimately and because of inability to identify to which bitcoins the illegit benefit where the whole pool of bitcoin might be fined with a ticket in conventional currency (that would be like the equivalent of saying that german franks are nazi money and anybody that is found in posession of it will be fined to have it confiscated). There is a high resistance to do that but since the analysis contains other portions with comparable uncertainty it starts to become relevant.
