There's another way to get into Bitcoin - a lump sum investment. This is for those who have a lot of money or wants to liquidate other assets and invest in Bitcoin. For them there's no reason to buy Bitcoin slowly unless it's in a bear market and the price is expected to keep falling. But we are in a bull market so it's impoartnt to get coin asap and maybe even be ready to sell them soon and buy back after the new bear market starts.
