DCA is good for investment and you have to have funds to be able to carry it out and accumulate it without going to it when it has not increased. To invest using DCA, you have to buy at a low price so that when it starts to increase you will see your return, so it is late to invest now because of the high price of bitcoin. Wait for bear and accumulate for next bull run.
The DCA strategy that is run gradually every week or every month for buying Bitcoin actually does not have to focus too much on price levels because such a strategy is only more suitable for investment and not trading which basically always looks at low prices and often wastes time waiting for price decreases to arrive. For investors who still want to invest in Bitcoin, it is actually never too late as long as they still have the capital to buy DCA within the time they plan themselves and of course it is regardless of the level of Bitcoin price differences in the market.
Agree with your opinion. This is also my understanding, please correct me if you think I'm wrong. When he said loss with DCA when the market goes up, you don't really lose, you just gain less than investing all at once. Likewise when the market goes down, you lose less than investing all at once. So, overall, DCA serves as a safety net to minimize losses, while limiting profits. The DCA method is more like value investing.
So it's true as you said, investing in bitcoin using the dca method is actually never too late. Even if you look at the analysis of several bitcoin observers also say that bitcoin will continue to rise until next year, so it's never too late. Analysis is not always right but can be taken to match your own research results before making your own decisions.
