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.
For anyone to think that buying Bitcoin should be considered a stupid act simply means such person doesn't have knowledge of what Bitcoin is all about as well as lacks the information about the predicted future of Bitcoin. As far as you aren't getting scammed by paying money for something that's actually not Bitcoin, you shouldn't have anything to regret investing in the real coin. That said, I don't fault people who prefer to invest in gold instead of Bitcoin especially people who are very knowledgeable about gold but lacks the basic knowledge of Bitcoin but personally, I'll always choose to invest in Bitcoin than gold.
