Buying and selling cryptocurrencies has been the essence behind the price movements of a specific coin. For somebody to acquire a cryptocurrency, someone else needs to sell it. There are buyers and sellers in each market that you can think of. They are distinguished because buyers think there is great potential in a particular asset and its price will skyrocket, while sellers believe its full capacity has been reached. Its price movement will be downwards for the upcoming period.
Cryptocurrencies sales occur mainly when there is more supply than demand for a particular coin. People feel like they are one of few who are holding the cryptocurrency, and the sooner they get rid of it, the better in financial terms it will be for them. At this moment, investors are panicking, which results in bots getting triggered and eventually selling the holdings.
This makes the price go down even further as people are constantly selling for a certain period of time, and almost no significant investor wants to enter and buy some portion of it at such a high price. This is an actual example of the bargaining power of buyers when they put pressure on the sellers to get them to lower the cost for which they are keen to settle. The fewer potential buyers of the particular cryptocurrency there are, the stronger their power will be, dragging the price even further down.
Eventually, sellers are put against one another, and they will need to compete to close their position and cash out. However, sometimes having a cash-out strategy pays off as you can exit the market in an early stage of the bear market and wait for a massive drop so that you can buy again at a discount. However, since the cycles cannot be predicted to perfection, we can only rely on some theoretical, statistical, and financial models to indicate at what point exactly we most likely need to sell our assets.
