This method buy the DIP and HODL is one of the most trading strategies or tactics in the Bitcoin and crypto market or in the investment cycle
that trading sounded off-topic, if am not mistaken here we don't actually use DCA for trading bitcoin and all that, we actually use it to accumulate more quantities of bitcoin to our portfolio. Which enables use to buy or purchase bitcoin at different price interval either when it's low or high. And we also have others good strategies for accumulating bitcoin like lumsump (going all in at once during a dip ) just as Tmoonz said.
when you think the price will go high but eventually it starts deprecating in value.
Also this method doesn't guarantee 100% profit believing that since the price is low at when is been aquire it will definitely hit at ATH
you sounded like someone that do engaged with shitcoins too much, if you are such do so in minimising such urge, when come to investing in bitcoin (not shitcoins) you don't have to bother yourself with if the price would rise and all that . Because bitcoin as already proven it self to be one of the best investment (and it is the definition of long-term investment). So if you have not Started to stash some of quantity of this epic coin (bitcoin) then I would advise you do so by using any suitable strategies to do so, but now I would encourage you use DCA strategy because of the recent increase in price of bitcoin. And yeah DCA doesn't guarantee 100% but also help you in buying at different price interval which would also help in minimising Risk.
in such case as an investor one also need to have two things in mind which is either gain or loss unless you wish to HODL for a longer period of time.
exactly so if you don't want to start using your funds to gamble, better start focusing more on bitcoin and how to to hold it for long... Though there are still risk in investing ( especially investimg in wrong project and bitcoin ain't such) but is still better than using your funds to gamble. Once you set your mind for holdl you would see the growth in your portfolio as time goes on.
