I think this only applies to those beginners who are afraid of taking risk and to those who haven't experience failure in trading. For a beginner who want to take trading they must read this and understand how the market goes. They will experience sudden pump or dump but they should not worry, instead take this as an opportunity for more investment as cryptos nature is very volatile and unpredictable.
In my opinion there is no common denominator apart from what I'm discussing here. In other words, it doesn't matter whether you are an experienced trader or beginner, you should at least get worried if the market falls suddenly and entirely unexpected for you. It may or may not be an opportunity but rationalizing it in the way you suggest doesn't look very appealing to me. It can bring you peace of mind, of course, but I don't think this is what most traders are looking for. They are looking for profits, not a feeling of being safe or protected.
