Anybody could learn if theirs a willingness on it. If someone is interested to explore then in could be more easier to learn. Just take it slowly and not to feel hopeless then at the end of the day you will explore and love the world of BTC.

There is no difficult to understand if you are deteremine enough to learn, if you are interested on something give some effort and willingness, just take it slowly, slowly but surely. Put some effort if you are willing to understand the nature of bitcoin. You will slowly realize the world of bitcoin someday.

For those who are not interested on that particular activities like bitcoin it is difficult to understand of course to the people who are started on the activities but if you ask there is no way not to be understand and also research and always update on what is new so that you are updated always on that particular activities you are joining.

TBH if a user only intend using bitcoin on general transactions like sending and receiving, the user doesn't need to know about the inner workings and technicalities accompanied by it. The option of sending or receiving money by just scanning a QR code is actually good for the average Joes who wish to use the cryptocurrency. Also, fiat with its inner workings and technicalities is also difficult to grasp, but do people need to know about it? No, because as long as the paper/coin is able to hold value and is transferable, they can use it in exchange for goods and services, just like what bitcoin does essentially.

1).Mining is the way the bitcoin transactions are completed on the network. All over the world, computers verify bitcoin sending/receiving.
“The blockchain and mining — they are, of course, related.” –Joseph Hsieh, co-founder of Expresscoin
“Mining centralization: to what extent will it happen in the long term, and what will be its effect on Bitcoin’s decentralized nature?” –Elliot Michael Lee, engineer at Braintree.
“Economic benefits of not having monolithic trusted third parties middle-manning transactions, as well as how miner incentives will keep the network flowing, and how digital mining compares to real mineral mining.” –Chase Sechrist, just a spectator.
2).Speculation-The price of bitcoin seems to always be in flux. It’s a rather volatile store of value because it is still so new.
“It’s confusing to everyday people to distinguish between bitcoin (currency) and bitcoin (Protocol).” –Michael Dunworth, co-founder SnapCard
“People are usually reticent about investing in Bitcoin because of the high price tag on 1 coin. They don’t realize that a bitcoin can be broken into hundreths of millionths of peices, so unfortunately lose out on a great investment opportunity.” –Jason Rosenstein, technologist and entrepreneur
“Why its value hasn’t grown faster.” –Luis Buenaventura II, co-founder and head of product at Rebit.ph

Exactly, if you really want to understand not just bitcoin but the whole cryptocurrency you must put effort on knowing more about this technology. Don’t expect someone to spoon feed everything to you, its time to stand up and adopt the system, if it still hard then do better.

Bitcoin becomes hard to understand because of two things: First, we do not completely understand bitcoin because we lack knowledge about it. Many people are afraid to take risk on bitcoin because the only knowledge they know is what they hear from news or sometimes the gossips. Another thing is, lack of interest, maybe bitcoin for some people is not their forte so they don't lend too much of their time to bitcoin.

Bitcoin is not difficult to understand in terms of using Bitcoin's algorithms. You need to be a real developer to understand, so for simplicity, you just have to protect your private.

Cryptocurrency and BTC are still in some shadow, many people are aware of his existence, but less than 1% of world population it actually owns uses it. The remaining 99% have a very superficial knowledge about it, or even have never heard of such a thing. Since we live in digital age and BTC is live last 9 years, probably the rate of adaptation should be somewhat higher, but for some reasons this is not the case yet.

I do not think it is difficult for people to understand BTC, most do not want to have any connection with cryptocurrency because all risks that come with it. Imagine how easy is to use fiat, you have money in the bank, you can pay with cash, credit card, online and your money is always secured. On the other hand there is BTC, you need to be your own bank, take care of safety, in case of hack/robbery there is no insurance and so on...

I think that most people in the world prefer the security of the existing financial system rather than experimenting with something new, but that will change with time.
