A real investor never thinks before investing that they can dump the market after investing. Market volatility is present at every moment, so it is natural that the price will change. There are many investors who think they are too smart and they just wait for the price of Bitcoin to drop relatively much. While waiting like this, many investors do not invest in the end. Since we have a reliable digital currency for investment, I think there is no need to think so much before investing in Bitcoin, but when we have the amount of money we have, we can start investing in Bitcoin with that amount of money and maintain the continuity of investment gradually. To start investing in a new situation, we should come out of the shell that the price will fall and start investing in Bitcoin with bold steps.
If a person invests in Bitcoin according to the DCA method, he will definitely be the most self-sufficient and will be able to hold it for a long time, so he will not have to worry about his Bitcoin investment and later he will definitely continue to get huge benefits in proportion to the savings made on the purchase price.
Your statement that investing through the DCA is a guarantee that the investor will hold for long is a little incomplete and it is good to set the record straight. The DCA method may encourage someone to think long term since the investment is not made under pressure but what will help an investor to actually hold for long is to invest with only discretionary income and to set up emergency funds. While we are encouraging people to adopt the DCA method, we should also add that investing within the discretionary income and setting up emergency fund are important practice that will guarantee that the investment is protect and not sold off under pressures. This is just one simple addition I needed to add to make your comment complete.
