Emotional control is hard to handle, it was really bothersome, especially, if you put every penny you have on BTC and haven't spare for your daily expenses.
Imagine, you can rest your eyes to see the price on the market every hour or even every minute, your heart almost crash.
A piece of advice which I quoted from other "Set your target price , then withdraw your BTC"
The number 1 rule here is that you just need to handle your emotions first in order for you to be more productive and don't let your emotions interfere with the things that you are working on because once your emotion interferes with your work, trust me that you will not be able to work well anymore just like on trading and bitcoin if you are seeing that the market and the coin that you've been invested in is currently dumping then that's the time that emotion is controlling you.
