Those people who thinks and said that Bitcoin is a scam must be living in a cave. If not, well, they are only trying to spread a FUD there and will take advantage of the situation by buying when the price dips a lot. Lastly, they can be the government or banks who thinks that Bitcoin is a big threat to their businesses.

There are still people who are aware of bitcoin and believes that it is legit. They can even use it but it's just that fiat is more legal on their country and let's admit it, it is much easier to use than Bitcoin. Another thing on why people won't use their Bitcoin daily like a fiat currency, is they think it's too valuable due to its properties (e.g. it has a very limited supply).
