Knowing basics like the seasons, bull run and bear run, what can trigger price to pump and dump, what halving means
A new beginner that wants to start his bitcoin investment as a no coiner does not need to know what triggers the price of bitcoin to pump or dump because it is impossible for anyone to know what will happen in the future as different scenarios and government policies/regulation and unforeseen circumstances can play out tomorrow that will affect the price of bitcoin to pump/dump. This is why that is useless. Also knowing about bitcoin season can be learnt as long side as investing. A new investor should start investing immediately, he has the money to do so, this will enable him accumulate more bitcoin and at the same time acquiring bitcoin knowledge. This is because he is investing for a long term in which he has all the time to learn more about what he is putting his money into, and he will not be faced with any challenge of running at loss because he will not be selling but only buying. What he needs to know is how much he needs to use to DCA constantly every week or month from his spare cash after he must have taken care of all his needs and expenses monthly.
The reason of investing is to grow that invest and build it up to a level that they investment will start taking care of you, and that cannot be achieved immediately, it will depend on when you started the investment. This is why delay is dangerous, and acquiring unnecessary knowledge as a hodler who is on a long term goal will not help you reach your bitcoin target quick.
So the best time to buy is when price dips, and sale when price surges,
A new beginner on his bitcoin investment journey does not have any best time to buy, because he is a no coiner or low coiner, he must keep buying regular consistent and persistent in order for him to be able to grow his bitcoin stash to the maintenance level overtime. It is investors who are in their maintenance stage or have almost reached their maintenance stage that buying at the dip is the best for them, because even if they DCA with little amount regularly, it will have no significance increase on their bitcoin stash. Remember that it is hard to know when the dip will come.
So the best time to buy is when price dips, and sale when price surges
Why are you planning to sell due to little surge in price or are you not planning to hodli for long term, because it is only when you hodli for long term that your portfolio will generate a good profit due to the compounding effect of your bitcoin portfolio. Investors that sell too quick ends up in regrets and lamentations because you might not be able to buy those bitcoin that you have sold at the same price in which you bought them 4 years ago.
