Bitcoin is very easy to understand, the problem is people are waiting price to reach its all time high price and when price reached maximum then they start investing in bitcoins and faced huge loss and then say that bitcoin is risky and difficult. Simple rule buy at low and sell at high!
The difficult part could actually be that angle where people think they can study and understand the market to know the right time to buy and sell, but that's not as difficult as the OP makes it seem, where I see it coming from understanding the technicality of bitcoin, which requires extra work to learn and understand that part, which, without paying much attention and sacrificing your time to achieve that, will actually appear to be difficult, which is why only a few are interested in that part of bitcoin.
The mindset that makes bitcoin as one of the assets to get rich quick or instantly makes us fixated on every movement with profit alone without thinking further in the end bitcoin is one of the investments that is still quite profitable but full of risks that sometimes make the idea of getting rich quick in bitcoin always not in accordance with the expectations felt by many beginners because they only like the profits but never consider the worst possibilities that could happen when in bitcoin because they don't want to know the risks involved.
Even though we know that bitcoin has a risk that is even quite large and we must be prepared for it as a form of consequence for the long-term investment that we make.
Until now, not a few people have the wrong perception with bitcoin because their initial stigma is that bitcoin is a get-rich-quick scheme, even leading to something that smells of crime that makes it difficult for them to be in bitcoin.
