Ok. Just a hypothetical question to see your response. Similar to those who say the world is over populated, but are the last to volunteer themselves off the planet (not saying this is you)

Even honest people that you trust for business could unknowingly receive and give you fake bitcoin in the event of a supply bug exploit depending on the type and how long it goes unnoticed. Imagine newer users onboarding their fiat savings around the same time period, or even older users making a massive trade, only to have received fake Bitcoin.
