Buying at the dip is not good for a new investor and that shouldn't be a barrier for him not to get started immediately, because you are a no coiner and need to start building and growing your bitcoin portfolio without wasting time. Since you are a long term hodler, DCA is good to start with because it will give you the opportunity to buy bitcoin at various price intervals. Just keep your bitcoin accumulation journey ongoing, rather than sitting on the fence waiting for the dip that you don't know when it will come.

Today ATH price will be the dip in few years, so why not start buying from now and save for the future when bitcoin price will be very high and the amount that you can use to accumulate a good size of bitcoin from one till four years with consistency and regular buying every week, will not be able to buy such quantity of bitcoin by then. Don't wait and delay the transformation of your future to the next level. The ball is in your court.
