First of all, a lot of people think that Bitcoin is too complicated and that they would not be able to understand it but that's just a big lie they tell themselves, due to this reason they make silly excuses that they cannot make the investment on their own. Another reason why people decide not to learn but choose to ask others help them invest is because they are just being too lazy. Bitcoin investment requires a little bit of research, learning risk management and also knowing how to use DCA, they consider all these as being too stressful.
For those who want to invest in Bitcoin and if they do not know anything at the beginning, it is not a matter of laziness to learn all the things about Bitcoin, including gaining knowledge about investment strategies. On the contrary, I have seen that some of my acquaintances are interested in learning about all these things about Bitcoin. I do not see much laziness in them. Those who do not have much confidence in investing in Bitcoin and cannot mentally accept price volatility are not interested in gaining knowledge about investing in Bitcoin. And knowing investment-related topics is not that difficult. It is only related to one's personal financial situation and mental desire and ability. There is no theoretical thing here that will take a long time to understand or that it will not be possible for anyone to understand these things.
