Actually there are three simple things that can be applied by everyone if they want to realize themselves to be more successful in their life. These three things are, the first is the will or desire to be better and the second is always setting aside time to learn, either through education or through skills that we like. And the third is don't immediately believe in the new things you see before you do your own research on what you just saw.
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.
I think depend one people mindset about their assets investing in which kinds will give much profitable at the future, some people still doubt with Bitcoin as worth investing assets because they are not really popular and understand well how Bitcoin price progress years by years . Many of them panic about bad news only and never learned with Bitcoin recovery to higher price after facing with bad news and success reached to higher price.
Talking about panic moment seems happened with new comer in trading actually on cryptocurrencies, they trade not based on their own research but another recommended and looks hype only, when the other investing on shit coins they will try at shit coin without research yet and the same when investing in bitcoin at the wrong moment when Bitcoin have reached too higher price.
