Many people/I come to crypto for making so much money, But I am in loss now, I want to share some rules and mistake that beginner or most of the people make that is harmful for there mental and physical health.
your points are so generic but still most of the time people ignore them and lost there money like a community member in of our local board forgot to save his key phrases in which he had like maybe few hundred dollars but after making few attempts he found a useful way to get that assets back by using some parent and child relations of wallets. Point is no wonder how experienced you are, mistakes are prominent.
You mostly focused on saying that we should do only that which involve less tension and attention i think crypto is full of both. Like without tension you will give no attention to market. These are ignorable when you are hodling BTC for like decades but if you are hodling them for shorter period of time like even for 1 year of 2 years then observing market is advisable because in this way you will be familiar with the market trends and sentiments. but avoid to fall into market sentiments traps while observing them.
investing isn't all investing if you don't have any spare cash for emergencies or for savings.
You are totally right, money is not to just store but to get used, a few days back I read a topic where OP says, he locked his savings of BTC so that in future emergencies he could not use them, in my point of view that was not a good idea. But he also mentioned that he will tend to use his savings from other sources.
