It really depends what is your investing approach. Passive vs Active?
With Passive, DCA is honestly by far the preferred stratergy to adopt, and that should not be affected by what's happening around the world.
If you take an Active approach, that is a completely different story. There are multiple stratergies for active for example instrinsic valuation as Buffett famously uses. You can use trend following. You can even use a mixture of both called value momentum investing. There are many others but I will not place an endless list.
Many at first glance may already assume not DCA = timing the market. It's important to understand what "timing the market" means. I completely agree that nobody can TIME the market.
However, I think there is a huge misconception that deviating from DCA equals timing the market which is extremely false. If that's the case, Professional investors/traders in investment firms or banks or those that do these for a living will not be able to make profits consistently.
Fundamental analysis, technical analysis, intrinsic valuations and market sentiments can guide you what is a relatively good price to buy at and if at the point of time the technicals show strong levels of support of possible reversal.
It's the same as if were were to buy our favourite shoes/clothes or bag etc... If the item was something we were waiting for a sale for a long time and there was a 50% discount, will we not be happy to buy it? Sure, 1 week later the store may sell it at 70% discount instead but you also risk the odds of missing out on a 50% discount.
It is impossible to say " Oh in 2 weeks or 3 months time the market will move down 10% or up 30% to this level." That's trying to predict/time it.
However, it is very possible to know what is a good price to pay for a stock. Just for an example, say Apple were to move down to $70 per share today it is an extremely good buy at such an undervalued price for a fundamentally strong company. Sure, after you buy at $70 it could go down more to $60 maybe $50 but over the long run, $70 would have been a solid buy and have a high chance to give you a high return on investment. Why would you only put in a small amount at such a discounted price?

We cannot predict/time the market, but we can certain READ it. Active however, is not for everyone, many do not understand or have been hurt by the market and hence, fear an active approach.
However, if you learn to drive a car properly, put your seatbelts, adhere to the speed limit and drive cautiously, driving is not as risky. It's risky when you drive without a license.
