For most, Bitcoin is difficult to understand, not only from a technical perspective, but in any sense. The mere fact that there is something that is completely online that you cannot physically touch is enough for some to find it difficult to accept that it has any meaning and value. Personally, I am convinced that it is completely useless to try to explain to some people what Bitcoin is because they already have their opinion that it is something bad, which will fail in a year or two.
Bitcoin is pretty simpler, sometimes even easier than some banks. People just dont want to learn something new
I would not agree with that, because how difficult it is to open a bank account, get a card and a 4-digit PIN and use an ATM or POS device? Try to explain to someone how to buy a BTC, how to keep it safely, and how to pay for a goods or service with it - the vast majority will have problems at any step.
