Bull runs can trigger strong emotions, such as greed and fear. While bull runs can provide profit opportunities, there is no guarantee that the altcoin will continue to rise without some corrections along the way. Stay realistic, set reasonable expectations, and invest within your means to take the risk. It is important to stay calm, rational and follow the investment plan that you have created. Don't get caught up in the emotional stress of the market and avoid making emotion-driven investment decisions.
There's more to learn about the occassions of bitcoin bullrun because it is always followed by the rise in the market price of other cryptocurrencies, though this doesn't mean they all rise at the same time or with the same speed but each experience it's own season as appropriately enough time for it to happen, but the excitement and fear that comes along this experience is what makes them think about cryptocurrency as an opportunity to take risk for the best or worst to come.
Bitcoin's bull run is not followed by rise in market price of other cryptocurrencies but rather it's vice versa, It always starts with rise in price of Bitcoin and then Altcoin starts picking up and once Bitcoin goes down Altcoins follows the same path as bitcoin is dominating at 52.55% market share. Excitement will be there because someone who has been accumulating the crypto knows that they are going to get profit as they won't have any fear but those who has not accumulated any crypto and wants to enter the market during bull run for quick profit are the ones who will have fear as there is a FOMO to enter market even when it's at peak and once you buy in there is a fear even when there is a drop of 2% as we start assuming that the coin has reached it's peak and going to drop down.
