If you are new to Bitcoin investment then it is important to have basic knowledge. If you do not understand what Bitcoin is, what is the function of Bitcoin, how does it work etc. If you do not have knowledge in all these things then I would say that Bitcoin investment is not for you. .
After gaining some knowledge about Bitcoin then you can gain knowledge about wallets. Because if you do not know how to invest in Bitcoin then I think it is a mistake to know about wallets first.
There are almost no people who are unfamiliar with knowledge about bitcoin because I am sure there are many sources that they can go to to find out the process of bitcoin's journey for now. I even doubt that you yourself understand the function of bitcoin well because generally people only use bitcoin as a step for investment and maybe basic knowledge about it is not something that is difficult to get.
For the storage issue, I agree because not many people may understand the level of security that is much better because generally people will consider the exchange as a place to store it. This is where knowledge is needed to find out and with the amount of information obtained, it is necessary to analyze a wallet that is much better at storing bitcoin much safer.
