Buying at the dip can also be done by saving any extra money that you have unexpectedly, like bonuses from work or traveling allowance e.t.c, so that when the dip comes, you can take advantage of it. Another way is that if you are DCAing $100 weekly, you can cut it to $70, and save $30 for buying at the dip. As a newbie in your early stage of accumulation, it is better to continue with DCA, and as time goes on when you have the strong believe on bitcoin, you can set a strategy that will enable to have the opportunity to buy at the dip, lump sum along side with your regular weekly or monthly DCA.
I'm not a fan of victimizing an obvious advantage over an anticipated one, in real sense, I would not advice someone to tamper with their already DCA accumulation journey because they're optimistic the there'll be a dip some day, and they buy with the money they've been cutting out from their DCA accumulation strategy, NO. In financial intelligence, you don't alter your already existing investment, to entertain another one, , instead you make new plans to contain a new Idea without hurting the previous one. Tampering with your investment routine before maturity is a very bad financial advice.
I'm a big fan of a win win formula and I believe from the time you feel that there's going to be the possibility of a dip and you're interested in buying it, you've to sort out another means of accumulating money for it, you can takeup a new job solely for that very purpose, and create a different account to hold funds for buying the dip, you can also cut down your spendings to be able to save more. Its better you find a way to make more money to buy the DIP whenever it presents itself than tampering with your already running investments. That way your DCA accumulation journey isn't tempered and your buying the DIP plan is effectively serviced.
