Agree, especially those people who bought crypto during the first month of 2019 and they sold it last December then they really have a great profit on it. Anyway, if we will buy crypto today, let's see and analyze first if are we going to hold for a couple of month or a year before cashing out. Let's make ourselves ready first before we proceed to buy.
It all depends on each person. Because everyone is certainly different related to finance. My own example, I can not do that (buy every week) because my finances are very minimal. And usually I can't hold long for not cashing it, always just pouring it. In contrast to people who can resist not pouring it, they might be able to look at their statistics.
