A: you spent it

B: it’s a currency

Here is how the thread went (too lazy for quantifiers and variables).

1. not A => not B

2. So Peso not A => Peso not B

3. You: But Peso A => Peso B

This is a non sequitur. „Not A => Not B“ does not entail „A => B“. That’s what I mean by you can’t conclude it (from the thread). You are however clearly free to make up new things and change the topic. But it looked like you were drawing a conclusion there.
