Buying every dip is easy to say, but difficult to identify the dip (for me at least!)
Every time the price of bitcoin drops I am afraid of the point that it is going to stop or it will be ongoing for a long time. Looking at charts and trying to make my TA sometimes prove me wrong!
Buying at the dip isn't anything difficult to identify, if you have been following the market price of bitcoin you would have discovered different moments of dip from when price first got to $100k it retraced and made a dip before setting a new ATH at $104k and then pulled back again. These pull backs could be identified as a dip except that at every point when the price rises there's a price mark you have set for yourself for price to fall down to before you get to identify it as price dip. You have to be aware that we're in the bullish season and as such you shouldn't expect price to fall down down below to declare a clear dip, that can only happen when we are going bearish.
It's best to say that buy bitcoin every time you have the capital to invest not just the dips better still dollar cost average every week or month when you have the capital. it's best to invest now because definitely this price that seems so high today would be the dip of tomorrow so if you buy today you'll figure out in times to come that you bought the dips but buying at any giving price you see today.
Of course bitcoin will make some fall backs but they're not permanent so they will keep going back making new ATHs hence you will be in profit in a longer range of time which is why we consider bitcoin a long term investment as it's not a get rich quick scheme.
If one is waiting the right entry price which is the dips you might end up not buying at all as market will always make some fake out that will put you on the edge thinking it will fall more then you can buy successful whereas it's not so as you might wait forever in the process of chasing the dips.
