Sometimes I feel that even while doing the DCA one should still look at the prices especially if we know that we are in bull market and the bitcoin prices are on the higher side.
If you ask me I will try to invest more during the bear season while as the price increases my DCA amount will start to lower. I think this is call smart DCA because in this case you will accumulate more at lower prices and it will give you more returns.

I don't think anyone is saying that looking at the chart once in a while is bad, what I know is not healthy is staying in the chart always and monitoring every move of the market. This will not only drain you or make you waste precious time you would have used for other productive things, it can lead you to anxiety which if you are not careful can make you take quick decision that will not help your portfolio. If you are using the DCA method, definitely you will know the price at the point you are placing your order, that is enough instead of running any form of technical analysis on the chart before you buy, just click buy and your order is filled and you make withdrawal to your wallet. Buying Bitcoin should not be too complex for us sine we already know that long term is the goal.
