Back to the basic concept, we come here not to lose, lose funds, the cause is from ourselves because we want to double the investment quickly and hope that in 2 or three days the investment value we trade can produce and increase from the initial capital. The reality is that most of them are big zeros, especially if market conditions are uncertain and their movements change. I guess buy and hold it for a long period of time, That's probably the real thing whether to use DCA or want it all at once.
The basic concept will go according to plan and must use a long-term strategy by implementing the DCA technique. It is very difficult to expect that within 2 or 3 days the investment value will start to increase in value because the movement is still unstable or for other reasons due to increasingly uncertain market sentiment. Bitcoin, whose direction of movement is very difficult to predict, requires investors to be more patient in highly speculative Bitcoin investments. Using the DCA strategy can enable you to collect Bitcoin consistently and accumulate assets depending on the amount of money you are ready to invest.
Buying at a low price and selling at a high price is one of the concepts and goals in investment. You can buy and hold it for the long term to get the profit you expected when you started investing.
Bitcoin long investment doesn't requires buying at low price in order to sell at high price, one can buy even at the peak price so far the intention is to buy and hold for longer period of time, prioritizing buying at low price to sell at high price can be more of trading strategy but when it comes to Bitcoin long term investment one can buy at anytime the money is readily available for investment irrespective of the price point , what is most important is achieving a good size of Bitcoin up to a reasonable amount
