Life is too short so we need to use it with right. If you have your Bitcoin, you need to hold on tight and not sell at a low price. Even if you need to wait for a year or two years, that is worth to do until the time come.
If you can sell at a high price, that will be your profit so you can enjoy with your beloved family. We need to have patience and wait the time come so we will not regret because of we sell our Bitcoin too low than we want.
That is why we must not in rush when we see the price down because that will change soon and the price will increase.
It's not about holding it for years as it not practical that you have an emergency situation and you are holding I don't belive in the concept that you have to hold it indefinitely until price increase if there are needs which has to be taken care of. I would rather says any emergency situation would be an exception and we should only invest the amount which we could afford to lose are which is not need for our survival as it shouldn't be like we are investing our grocery or bills funds to earn quick profit and market goes down and we are left in a miserable condition.
That is why if you decide to have investment, you must allocate that money for specifically for the investment so when you have an emergency situation, you will not disturb your investment because you also prepare the other money for that emergency or urgent situation. Your investment is your responsible, same as your other needs in your life so you must know how to manage all things you want to do. Yes, you must only invest the amount you can afford to lose so that will not get any problem with the investment or other things.
