You guys are laying too much emphasis on investing small amount per time forgetting that there are different approach to bitcoin investment. If I have $10,000 as my discretionary income to invest in bitcoin in a time like now that the market is making some corrections, why should I stress myself investing $500 regularly when all the money is meant for investment and I have good buying opportunities? So long as you have discretionary income and have set up emergency funds, you can use any method to enter the market since the goal is to hold for a long time. I will even feel comfortable buying bitcoin anytime I have the opportunity to that I will not be tempted to use the money for something else.
This is a good approach considering that the funds you use to buy are surplus funds
(discretionary income). I believe that the decline that occurred was a stroke of luck that does not happen every time, you took advantage of the opportunity to buy at a low price, where you could get more Bitcoin than if you had bought when the price was at its all-time high, instead of waiting for the price to fall further and letting the money sit idle.
I'm not saying that the DCA method is bad, but when you have the opportunity to buy the dip and the money is there, an entry at discounted price is not a bad decision. You can even make such entry while still continuing your DCA method.
Actually, DCA is still relevant, especially for new investors who want to accumulate Bitcoin. This method is highly recommended, investors don't need to wait for the best time to buy, buy whenever you have the opportunity. This is useful for maintaining consistency in long-term investing.
