It's a scam or ponzi scheme. I think the public mistakes behavior like that of SBF, Mashinsky, etc as somehow being an inherent part of bitcoin.

Good question. I see two:

But I also think there's a big myth amongst Bitcoin adopters as well.

That myth: Bitcoin fixes everything.

Gresham's law being used to explain or justify spending euros and not Bitcoin. It shows a lack of understanding of Gresham's law and the issues around gold coins' coinage.

For more details, see my frustrated rant here: #224557

That it boils the oceans. Lol.

That it isn't valuable.

Probably that bitcoin is bad for the environment.

That it wastes energy.

BTC is too volatile, its supply is too centralized, and because its inherently yieldless it's an inferior asset.

All of them untrue once one spends just a few minutes thinking critically about each item in turn.

"i cant understand this"

It's too complicated (because the global fiat system is simple)

It’s for hackers and criminals

That is used mainly by criminals.

It isn't backed up by anything, therefore it can't be trusted

Probably one of the highest inhibitor and misconception of what is bitcoin. Or how someone can use it.

No matter the value, type of asset, or its utility. Bitcoin is seen as too expensive in both bull and bear markets.

Unit bias.

"That you have to buy 1 whole bitcoin and that is nearly impossible now because it is so expensive." Although my wife is not a bitcoiner and tolerates me talking about it for a little bit, some of that knowledge is sticking. She was walking the other day and some women asked her what we were in town for (we were there for a bitcoin conference) and this is exactly the statement they gave her. My wife correctly told them that you could buy a small fraction of a bitcoin and do not need to buy the entire thing and that it isn't subject to the whims of politicians or inflation. I was so proud of her!

That it doesn't fix everything

ponzi.

Id say the most topical one right now is the belief that its shadowy terrorist money.

This is only a certain group, which is people who are in favour of a local currency. They find the redistribution of Bitcoin unfair and think it's beneficial to those who have lots of Bitcoin and unfavourable for those who don't have Bitcoin.

This group also that is highly speculative and that the pumping and dumping of Bitcoin is a huge problem.

It’s for somebody else

I think all of them are still prevalent with normies to some degree. People are happy to jump from one to the next every time a new msm hit piece comes out or some crypto scam implodes. They'll latch onto anything that keeps them from admitting they were wrong about Bitcoin.

Bitcoin = just Bitcoin. We need people to start realizing that Bitcoin is much bigger. It is a whole world of its own, including cash options, privacy options, and much more, and that this separation of concerns is a feature, not a bug. For example, I don't like to say Bitcoin has a "scaling problem," because I don't see it as a problem but a feature. Bitcoin has payment via Lightning by design; I consider Lightning to be part of Bitcoin (and NOT wanting to compile it into Bitcoin Core). The same logic applies to privacy options and many other things. But for many, the level of comprehension is like this: "Bitcoin Lightning has about as much to do with Bitcoin as gold to [fiat]." (an actual quote from somebody)

"It's a scam" and lumping it in with "crypto"

"It's not backed by anything"

"The governments will ban it"

"It's a speculative asset that has no real use case, just buy and sell for a bigger price on an exchange"

i didn't understand the potential of Bitcoin until i started to understand the concepts of fiat money and fractional reserve banking and the larger global economic system ... which is to say, i think the "myths" about Bitcoin run downstream from misunderstandings about how our current monetary system works.

i still barely have a grasp on it, relatively to how much there is to still learn. but i don't think Bitcoin will start to be embraced until a larger chunk of the population has a better understanding of how much of a scam the current system is.

also, yes, all the altcoins sort of tarnished the concept of cryptocurrency in general. (perhaps by design?)

Other than what's already mentioned.

• Bitcoin is expensive to buy (no mention of sats) • That Bitcoin will go to zero

Lots of the FUD is just plain lazy journalism though.

Journalists not keeping up to date or regurgitating old articles.
