When anyone starts seeking for immediate all-knowing about bitcoin, he is already having that traders mindset. Panic sales don't just happen in a day, this is a product of continuous market monitoring and speculative investment. Anyone who invest with the intention to Hodl for long, won't spare a time to watch the chart. A true understanding of bitcoin would allow you know that bitcoin volatility means that price that's up today could be down tomorrow and vice versa; it would also allow you to understand that no matter how long a market correction occurs, the probability of a new ATH is still extreme and could only be achieved in long-term holding.
Investing to monitor is exhausting and also a trading skill. Some investors with trading mindset would hardly survive in long-term bitcoin process.
Price list monitoring does not have any harmful effect on investment, if you invest with unnecessary money and commit for a long time. If you invest with necessary money and you invest with trading mentality then the market list will be harmful for you, rather your thinking is somewhat harmful. For investment, you have to add your money to your portfolio in such a way that you feel like you are putting the money in a box that is impossible to open before a certain time. That is, forget about the money after investing and wait for the goal to be achieved. If you monitor the price list again and again during this time, you may not have any problem.
