Of course we have to be patient to do any work. Likewise, we have to be patient by investing in bitcoin. Because Bitcoin is a digital coin, it is sometimes up and down. So you can invest long term in hopes of more profits. That's why we all have to be patient for more profit.
But just standing by and being patient is not productive enough I suggest that we should utilize each moment specially during the market crashes. There are a lot of things we can do while holding and being patient, you can even consider to buy more of your investments or start a new one when their market value is very low or you can consider day trading to maximize the profit for each market movement.
