An example here is Bitcoin where you believe and invest in Bitcoin based on your own knowledge and research on Bitcoin. Not based on what other people say, although what other people say can also be taken as an initial reference before conducting further research on our own. And as for controlling emotions, I think everyone can control them well as long as we don't panic about what other people are saying.
Learning to accept consequences is an effort to keep understanding important lessons from every aspect that we live. It is important to remember that everyone must have the ability to control worry and ask each of us where is the investment model that does not involve risk?
The simplicity of bitcoin is contained in a store of value and bitcoin has the power to defend itself under any circumstances, Covid-19 is a reference that the collapse of economic resources in various sectors does not affect bitcoin to reach its highest peak. The next question is what to worry about for bitcoin? although people talk nonsense about investment risk and I agree with your argument, that analysis and knowledge is a source of strength for people who worry too much.
Buy and Hold Bitcoin I will be a winner!!!
