Fortunately, not as many people in the space are stupid enough to buy something offered as BTC but in reality, not so much so.
These days, it's very easy to proof check such things in a minute or two.
Buying Bitcoin will not be considered a stupid act by everyone, but selling Bitcoin to buy something else that is not as valuable as Bitcoin can be considered a stupid act by some people who are already familiar with Bitcoin's performance. But for other things like gold, I think it is okay to sell or release it for something else even though gold itself can also be relied on as a good store of value even though if you look at the level of profit that can be obtained, it is not enough in a short time.
