Your analogy is really bad. Let's make it simple. Yes, you don't need technical knowledge to learn how to drive the bus but you can assume that it is safe because the driver has gone into training and when something bad happens to you, you can blame the driver and the company which makes the travel safer than just riding it your own. When you ride the Bitcoin train, you are on your own. When you lost, it's your lost, when you gain, it is your gain. You are on your own, you can't blame anyone but yourself.
Next is gold, is has been around for thousands of years now and has been proven to have a use in our society by the masses. Its real-life usage makes it more appealing to people and investors which is why it is safe to invest in it. Investors are safe because they know how gold works in the market and how it is being used to make our lives easier. Gold is tangible and can be used to create gold jewels or computer parts that make the computer faster for example. Bitcoin is not tangible which makes it less appealing to investors.
It is simple, you use a bank, bank store your money, you get interest per year, and it is safe if you don't touch it. You don't need technical knowledge to know that bank is the way to store your money, and it is easier to do it. You see, safety is what keeps people from using it. Unlike Bitcoin, you need simple computer knowledge like installing, and stuff to make it work (which is hard to get guidance with sometimes). When it comes to investing. Investing in Bitcoin is not a joke, it is not regulated, it is too volatile to even create a slightly accurate prediction, and it is driven by hype from those investors. Not to mention that when you are scammed or hacked, no one can help you but yourself (depending on the amount) and it's hard to trace back the hackers or scammers. Although it still not that safe to invest to, Bitcoin's freedom still makes it appealing to other people.
I'm not trying to make Bitcoin look bad but let's look at the reality first. We need more years of development to actually make Bitcoin appealing to people. Although it's not as safe as other transaction, I still use it because of freedom.
Yes we should not scare people. People can learn fast now-a-days.
Cant their be bank alike who will handle Bitcoin same as fiat for people who are less technical, because that's what our next step will be.
Can i just ask will you ever start a Local Independent Micro exchange just for your neighbourhood or community. This will save people from sending their personal information to some offshore exchange with zero liability and people can trust as i trust my bus driver.
