No doubt people want physical things they can touch and feel. Many still think bitcoin is a made up stuff that isn't real. They still want to be able to feel their money been spent that's exactly why they intentionally don't want to learn about bitcoin and not that it's too difficult to understand. If you're already good with operating your mobile phone you won't find it difficult learning the sending and receiving of bitcoin procedures.

It took me not more than minutes to learn them meaning it most likely won't take others the same. All I know in using bitcoin was self taught. You do not have to go reading books how how to do them when you can use a visual representation via youtube or personal coaching but if that's what you enjoy doing than that's cool. The best way to learn something fast in the industry is through experience.

If we look at the Covid-19 situation in the United States we can see that most people have been infected and died there even though they have advanced medical care and economic strength. There has been some improvement in the situation as a result of the desperate efforts of the government and doctors. On the other hand the situation of Kovid-19 countries in South Asia has been deteriorating over the last two months. Of these government incentives and concerns can help the human race. The government has relaxed everything and resumed business so that this situation can be overcome.

There are currently three ways to steal Bitcoin. First, hackers infect crypto asset exchange servers with special malware via e-mail, websites and popads and infiltrate devices. This happened with the Binance hack last year.
Second, take apart the Bitcoin hardware wallet and get the seed phrase. This has been practiced by Kraken against Trezor.
Third, hacking into the Bitcoin blockchain network itself through “51 Percent Attack”. This third method is considered expensive, but has the potential to get the largest loot than the other two methods. This third method, according to observers, will cost up to US $ 21 million.

I think Bitcoin is not difficult to understand, the most important thing is that we have the intention to learn everything about Bitcoin.
Because all information about Bitcoin is also not difficult to obtain, it is already spread in the internet world. In fact, this forum is quite
complete with information about Bitcoin that I can get.

All traders want to always buy Bitcoin at a price cheaper than the market price. Apart from buying and selling on the ordinary, centralized crypto asset exchange, there is another option, namely a peer-to-peer exchange. In this exchange, asset prices are not “regulated” by the exchange manager, but directly by the users. In principle, a peer-to-peer (P2P) exchange is a crypto asset exchange that is similar to an online shop, aka a marketplace. The role of the stock exchange manager is only to bring together the seller and buyer of assets directly on one platform. In other words, for example, if you want to sell Bitcoin, you have a trading booth on that platform. It is also possible to place ads on that platform by specifying the selling price of the asset. The advantage of an exchange like this is that the seller is free to determine the selling price as he wishes and the buyer can freely look for price variations on the exchange. Buyers can even get a much cheaper price than buying on a regular exchange.

Is there any place I can redirect clients on my website to a website that allows you to send them paypal money and automatically sends bitcoin to the address you specify?

I want to refer my non-technical clients to this place to provide them with easier usage.

In my opinion, a world war is literally the worst thing that can happen to humanity, with or without bitcoin.

Wars happen because countries can't pay up their debts, so they "pay up" this way. (Again, in my opinion, no misunderstandings)
In a war, the fiat loses its value. I had a discussion with a friend about what could happen to bitcoin in a war. He said that it will surely collapse. I am not so sure about it.

Although, think about it for a while. In a world war, the last thing someone has is access to the internet. Would bitcoins lose their value?

History has shown that gold is the money that "reborns" fiat. At least after a war. I would like to read some thoughts.

Searching from the internet will give us the result of what we want to know because we can browse in many website sources that we need to help us learn and understand something such as cryptocurrency. We can't depend on other people to gain knowledge because we need to search for ourselves. The more we can learn, the more we will know about something. The internet gives us an easiness to explore and learn cryptocurrency because I am sure that it will help us find what we want.

As long as we have passion about something, we will spend more time to find the answer, and we will search for many websites. The situation right now is not the same as a few years ago before cryptocurrency became popular. I am sure that we can find much interesting information related to cryptocurrency.

It fine to have a textbook but there is no available at this time talking about crypto. Well, it might not important to have it because the internet is also a reliable source that can help us to understand crypto and it is the fastest and easiest way to make a search. In fact, you can find a lot of sources online that a textbook might don't have but of course, you should also evaluate if that sources are legit or not.

What has bitcoin done to me? A whole new way of thinking and developing. Blockchain. No one controls it. Neither you are a government's man neither you are a simple family guy, you just can't.

Also, as @mk4 said, the ability to hold your money without having them physically or stored on a bank is liberate. And fascinating too.

Dedication to learning is the way forward. Interest is another too. And if somebody has no interest, dedication will not be reached. Interest is what makes learning easier , interest is important. With interest, learning bitcoin is very easy.

Bitcoin is certainly hard to understand, but that doesn't mean that it's hard to use. Most people can drive a car or send an e-mail without understanding the internal combustion engine or Simple Mail Transfer Protocol (SMTP). And certainly both of these were considered “too complicated” for the masses.

Not everyone loves to read book since majority right now is on the net and there are so many articles and youtube videos are truly helpful for people to understand on what is bitcoin and how it works. But I on the other hand I agree that there's a book related on this topic since its good to have an option to scattered the information about the bitcoins.

If I were to ask it is really difficult to understand how does the bitcoin works, what is it and also what are the meaning of the terminologies we are using when we are inside the crypto world. That's why when I first enter the bitcoin talk campaign I find it difficult because there are terminologies I don't understand like the word binance but now I can completely understand what is it because I am staying here for years.

But there are other options like audio book that they can listen, like Bitcoin's White paper.

Being a community and bitcoin supporters, it is already being used as payment worldwide for specific use and for the merchants that are okay accepting it. But as for the government, they can't rely to a decentralized cryptocurrency.

There are already plans that have been on the news about creating their own digital cryptocurrencies. They'll only create fiat and migrate it into digital just like what we're having right now for each countries that has own local cashless payment methods.
