I see no hurt in wanting to apply the DCA approach but first consult my trading chart to know the market condition.
DCA is not a strategy of trading so I wonder why you would want someone to consult your trading chart before doing there normal DCA it actually sound somehow to me or are you mistaken DCA strategy for a trading pattern? Actually DCA strategy is not dependent to any form of market price or anything before accumulating so there is no need of consulting any chart before someone can starts accumulating.
It seems that he misunderstood the meaning of DCA, he needs to be directed to a further level so that he can interpret this strategy correctly. DCA strategy is a straightforward investment method with very high efficiency, investors can divide a certain amount of investment into several different amounts instead of investing it all at once. DCA also offers convenience and investors can invest even with low capital in a certain amount during a specified period. Therefore, the reason many Bitcoin investors apply this strategy is because it is a safe long-term investment method.
