The number of people in this forum combined together with the number of people who know a thing about bitcoin compared to the entire population is not that much, the community is still a mote in comparison, so be forgiving and understanding to the people who do not know about. OP sounded condescending just because they do not know about it, do not be like that. If there is no way that they know about it then adjust because they are your clients and you are offering your services to them not the other way around.

According to statista.com, only 70-80% of United States adults have a pc a laptop. Not all of them are even connected to the Internet, and some just use them simply for minesweeper or to do basic work with documents. No wonder that with population close to 330 billions, there are people who dont know what Bitcoin is.

 

You know it is very common and I was introduced to bitcoins by someone similar a few years ago when I was working and I usually used to accept payment in Libertty Reserve (it was a prominent payment method during those times and very popular just like Perfectmoney is today) so I was working for a client and they offered me $200 for the complete project (I'll keep the project private cause of NDA) so they offered me Paypal and I refused and what they said next was bitcoins which was completely new to me and that is how I first got to know about bitcoins and then slowly I rolled into it and now hardly ever I accept payment in any other method unless there is no option left.

Hence, word of mouth is a great promotion for bitcoins and I believe the biggest power of decentralization since no one controls them you always know that someone is not promoting you for referral commissions.

This is due to the numerous scams and in the ransomware attacks which asked for bitcoins as a payment method. Moreover the news channels also describe bitcoin as a currency that is used on the dark web for illegal purposes, after watching this do you believe a person can try to buy bitcoins. Also there should be media campaigns that should advertise bitcoin as a currency and as a method to send money across borders without any significant fees and also we need to change the people's mindset towards digital currencies so as to increase the awareness and acceptance world wide.

From my point of view, there is nothing to be surprised off because there are still a lot of people who don't know about bitcoin and other cryptocurrencies. Also, not only in the US because I think about 20% of people only know about bitcoin and 80% still don't know about bitcoin all over the world. It is the reason why other people advertise cryptocurrencies for more people will buy crypto and bitcoin.

thats not surprised me, why ?
i have 2 reason about this...
1. Almost bounty project, they do not allow for US people to following the project.
2. Maybe, lack of promotion about bitcoin at US country.

I think there are only 2 reasons above that cause this to happen

That is why bitcoin needs longer to be known by the people, so they can use bitcoin as what we did.
We can still introduce bitcoin to people who don't know about bitcoin, but we don't need to force them to learn more or use bitcoin if they don't want it because that will make them hate bitcoin.
Even if people connect to the internet, if they don't search for more information about bitcoin, they will not know, and they will skip the information that they found on many websites.
We can invite them to learn about bitcoin, and maybe we need to use another approach that can make them have an interest in bitcoin.

Not early surprising here in our neighbor 9 out of ten people do not have an idea what Bitcoin is 4 out of 10 have read or heard about it but do not know what it's all about, this technology is still young and our generation has a huge task to promote and introduce this technology, we are lucky that we are already here and benefiting from this technology.

Probably, their country does lack of promotion that's why they are ignorant about the existence of cryptocurrency, it is just easy as that. If the government promotes the use of cryptocurrency freely and inform the people how it works then Americans could achieve mass adoption in Bitcoin easily. I know that it is not that easy to do that, but it takes a lot of process before the people to understand how bitcoin works.

It should've all start with the government. Not only Americans or US citizens who are not that knowledgeable about bitcoin. In some other rural areas in every country, they are not the introduced in the use of digital currency due to the lack of knowledge about advancement of technology. Once the bitcoin achieve mass adoption, transactions will become faster and more secured, just like what the OP wants to be paid.
