Everything you said is important, especially for beginners, but the part I quoted is the most important I think, because anyone can be a victim of fraud. So let me explain more about it, people should be aware of scammer traps, most people who experience fraud are usually due to negligence or ignorance, therefore it is best to avoid anything that seems "Too shiny" or "Too Good to be True", and avoid anything that gives you extraordinary expectations, such as "Free Crypto" for example, so remember that nothing is free, and there is an important saying that "if something is free, you are the product" ( I found that it was from the words from Richard Serra, in 1973).

Regarding the using of multiple wallet is also important. Just imagine if one day we are careless and fall into a scammer trap, then we will most likely experience a big loss if the wallet we use is a wallet for storing and also for daily use of the cryptocurrency or Bitcoin that we own. Therefore, we should differentiate between wallets for daily use and wallets for storage purposes, for avoiding major losses due to the possibility of something undesirable happening. Personally, I keep my wallet for safekeeping or storage in a careful manner, I try to keep the wallet off the internet as long as possible and store it encrypted on a drive, as for the paper wallet, I also store it very carefully.
