Bitcoin is close to its highest value in years, just 5.56% away from its previous ATH of $69,045. I predicted it would reach the ATH this month, and it is guaranteed with only 4 days into the month. The increasing adoption of Bitcoin at both retail and institutional levels has rapidly driven up its price, putting us in a position to hit $75,000 by the end of the month. While this isn't a prediction, the market looks more positive than ever.
I've heard, "The best time to invest in Bitcoin was yesterday, and the second-best time is today." Even if you think it's too expensive, you can buy fractional shares of Bitcoin. Use Dollar Cost Averaging (DCA) to gradually invest a fixed amount regularly. Only invest what you can afford to lose, and don't let emotions drive your decisions.
Personally, I prefer DCAing in a Bear Market when prices are low. However, you can DCA in any market. In a Bull Market, you get fewer coins per round, while in a Bear Market, like the "Crypto Winter," prices drop significantly. In a Bear market, I DCA to the bottom and halfway back up to my entry price. Then, I might double the amount to buy the dips up to my entry price. This is not financial advice, just an explanation of how I approach DCAing into Bitcoin and Altcoins.
