It's important to have some money in fiat money on stand by so you can buy the dip when the prices fall down.
Yes, having reserve funds in fiat is also important. Because it can be very useful when there is a big correction in the market. because we will be ready to take advantage of a downturn by buying more. Meanwhile, if we don't have reserve funds that can be used during a market correction, we will definitely be quite annoyed because we can't take this moment into a profitable opportunity. I always have this too. That is, I always have USDT which I keep in my wallet which I always use or use to buy when the market is deeply corrected. And that's what I did to DCA bitcoin. But mostly I use it more for short-term investments. That is just to take advantage of the reversal momentum in the market.
