It's not necessarily easy, and frequently when we interact with others in terms of talking about bitcoin, we are likely going to ongoingly find instances in which we either do not know the answers or we are not able to explain very well in order that the person on the other side of the conversation sufficiently understands and/or is able to get enough from our conversation in order to research into the matter further. People learn at their own pace, and frequently they have difficulties finding information, and even if we might share information sources with other people (by sending links), they might not read matters that we sent to them or be inspired to look into the matter further, in terms of information sources that we had provided.. and sure, the information (like we presented) may well not be "on the news" from the sources that they are accustomed.
I like people who do not take a word for what they hear, those who think and check any information that they are given for review. But people are often lazy and it is easier for them to miss something that may take a long time to study than to understand this issue.
Bitcoin require a lot of time, since this is a very broad topic and in order to understand it, we need to have a desire for this, so that a person wants it himself, otherwise this is will be a superficial acquaintance, according to which he can remain with his original opinion. I believe that there should be a time for everyone to embrace and understand bitcoin, those who do so early will be able to gain an advantage.
Yes.. it probably takes many exposures (more than 6), and if the exposure is misinformation, it could take way more information to clarify inaccurate information rather than to just understand accurate information... sometimes the inaccurate information might line up with a person's view of the world and perhaps even the inaccurate information will reinforce other inaccurate information, so then the inaccurate information might become more believable for some people, and more difficult to both understand and start to give credibility to the accurate information.
In the case of bitcoin there are a lot of different angles in which there can be difficulties in understanding, even beyond a potential belief that "government has to approve monetary-like assets" or "debt is needed in order to facilitate 'growth' and "prosperity.'" So, it could take a long time, just to understand bitcoin's role, and of course, there are other angles that have been mentioned, too.. in terms of the various other kinds of misinformation in regards to bitcoin that people will tend to believe.... such as it does seem to be so fantastical.. and that there is confusion between bitcoin and crypto..and those kinds of confusions are purposefully reinforced and contributing towards difficulties for normies to really wrap their heads around what bitcoin is and what makes bitcoin valuable for everyone as a kind of "people's money."
