Emotion control is essential when it comes to Bitcoin investment. Doesn't matter which one or where you buy, it could be the very top or the bottom, it shouldn't bother you a bit. And I don't think having good emotion control would lead to panic. If the vision in to Hodl for a long time, then it is better to just forget about those coins that you own.
And future profits or loss is uncertain or unpredictable when it comes to Bitcoin investment. You just know that this will happen, and this event will lead to this, which will eventually push Bitcoin's price up. We all know what I am talking about. But the exact amount or the exact time is unknown. So why think and get panicked about something that is not there yet, and only the future can tell the difference?
Focus on your goal. Set a target and just wait till it's fulfilled. Could take days, months or years. But it will happen eventually. So focus on that.
