You can also get started without understanding it all
I disagree with you that anyone can invest into bitcoin without have any knowledge of bitcoin at all. You must have the basic knowledge of bitcoin before you can start your bitcoin investment or someone is there to guide you. If you don't know anything about bitcoin, how will you know that you are invest in a long-term and that the price is volatile and you shouldn't sell in panic whenever there's a dip.
This is the reason why a lot of people jump into bitcoin investment and think that it's a get rich quick scheme and run at loss because they fail to learn the basic knowledge of bitcoin and understand how they can plan on investing and hodli for a long-term.
I can take myself as an example, in the beginning when I heard about bitcoin due to lack of the basic knowledge of bitcoin, I thought that it's only for trading and never knew that investing in it for a long term plan is the best. I also invested in shitcoin because I don't know the difference between bitcoin and shitcoin because I didn't make any research. Anyone who wants to start his bitcoin investment must have the basic knowledge of bitcoin and increase his knowledge as he is building his bitcoin portfolio.
You don't need to have the knowledge of a school teacher to understand Bitcoin. Anyone with basic knowledge of Bitcoin and a reasonable income can invest in Bitcoin. Only those who invest and want to learn at the same time can move forward quickly.
Again, if someone wants to understand the real taste of Bitcoin, then they should not sell but buy and hold for a long time. Many people fall short of their original goal before reaching their desired goal. They sell out of fear or panic and destroy their long-cherished dream. So if you really want to invest, then you should buy Bitcoin very quickly without waiting.
