Some people prefer to invest a large lump sum all at once because you might end up with more Bitcoin quickly. But there's also a chance you'll end up with less. To decide between these two methods, you need to think about the risk involved.
It depends on the market behavior, I would prefer to go all into Bitcoin if the price fall to 10k per BTC, that's a once in a lifetime opportunity in 2023, this move is worth the risk because it will surely recover very fast from this sweet spot as many whales around the world will want to buy at the price too.
If the dip is very high then it's a big opportunity, compared to small accumulation using the DCA strategy every month or week, right now BTC is 26k and counting but it's different from seeing BTC at 10k right now.
The lowest that Bitcoin have dipped since the beginning of this bear market was 15k to 17k and anything lower seems impossible again, the worst that could happen now is retesting the base, do you see the difference now? Some risks are worth taking because of the once in a life time opportunity they creates.
