As much as the Bitcoin, altcoins, ICO, the whole of Cryptocurrency and its jargons with blockchain can be seen as complicated, there are levels of perspectives that can be disclosed gradually and also dependent on the area/location or class of persons being informed. I believe it can be best simplified; brought down to the level of their understanding. The complex aspects can be left aside and can be enlightened when the time comes or when it is needed.

if it is too complicated for people to be. maybe that's true too. but if they always learn and ask questions. I'm sure they can. because there is no science that can not be mastered. as long as there is desire and strive for sure they will.

if complicated it must be especially for people who have never held a digital tool. because some people. because it is far from the crowd and the lack of this signal is the main factor they are left behind with the digital world .

The primary approach in dealing with bitcoin, is knowing the interest of a person and thyself. It will be easier for aspiring bitcoin users if they are really interested in learning and understanding its background, nature, system and just anything about bitcoin that can help them through time with using bitcoin. Most people focus on the way they see bitcoin, as a source of having privileges that would very much benefit them but not as a subject matter that needs to be thought of and learned properly making it somehow a difficulty in understanding it immediately.

I can not determine the level of exposure of the user community in the crypto world. However, it is possible that bitcoin will have a limit for age. Because bitcoin needs basic capabilities from the computer or the internet, users aged 50 or older. They can hardly reach and grasp the usage or operation process to send and receive bitcoin.

Every thing is complicated when it is new, and it gets simpler when you are getting used to it, when you want to learn about it.
And still we does not know the mechanism behind the maximum technology we use in our daily life, but we still use it. Similarly one can take the advantage of the bitcoin with out having deep knowledge in the blockchain. 

Oh naa I don't see it as being complicated or difficult to understand. In fact, anyone can understand Bitcoin and blockchain(somehow) so far as the person is ready to learn. They just have to avail themselves to learn, and that's all.

The idea behind blockchain technology needs to be clarify to the public especially to those who have no any idea aboutit yet spreading accusations and false information to others. The main threat to bitcoin and cryptocurrency itself is the misconceptions that other people has created just to eliminate bitcoin in the market. If only they understand this industry more, they will accept this system.

At first, bitcoin is too complicated to ordinary folks. Which 100% sure that they will think bitcoin is illegal because Ypu can refer bitcoin as "Easy money". That is the reason why they are thinking bitcoin is illegal. But the purpose is bitcoin is to have a secure transaction which is the blockchain technology which is currently trending right now. But if ordinary folks read about basics in crypto or investments or concept of bitcoin. They will not think bitcoin complicated again.
