Buying Bitcoin aggressively with the fund set aside for basic is one of the step for every Bitcoiner to sell at lost price no matter the good intention s/he has and no matter how people make wrong decision with their Bitcoin investment we can only make them understand the fact about how to accumulate Bitcoin profitably because even if you're Satoshi and you provide them the right guide they will still end up following their path.
Your response is a bit contradictory to me because how do buying bitcoin aggressively a step for bitcoiners to sell at lost. Anyways while i am still trying to grasp what you are saying, i can tell you that there is no such thing as bitcoiners selling at lost price while investing aggressively but i can put it in a clearer way for you. Buying aggressively can only depend on the size of your discretionary income such that you can chose to invest all without minding how big the amount is since it is still at the level of your discretion. It can also depend on how big your income is and how little your expenditures are that will tell if you will have enough discretionary amount to invest aggressively.
Buying Bitcoin aggressively is more beneficial when there is Dip because you will be able to buy a large figure of..., and buying aggressively depends on our financial capacity, some investors make mistake buy buying Bitcoin aggressively even when they are not prepared and then later run they are panicking because of the little dip that will happen.
Using all your discretionary to invest during a dip to me is not actually right because it is Always good to have small savings ( discretionary) even after investing for security reasons.Yes you are correct however if you have a strong backup funds which is emergency, reserves and float funds and there's a dip you can be using all your discretionary income to accumulate aggressively because you won't get into a problem since you already have a strong backup funds but if you don't have a backup funds then you need to start building it along side your Bitcoin investment meaning you we have to divide your discretionary income parts one for your backup funds building and another part for your Bitcoin accumulation.
The real fact here is that if it's an amount of money you can do away with for a very long period of time, their is nothing stopping you from accumulating aggressively during a serious dip as long as your source of income is there,
your emergency funds and backup funds are in place, because they gives you the leverage of doing so without making your holdings defenseless if their is any emergencies that arises after then.
Then as for the aspect where most Bitcoin investors invest aggressively with during a dip with the money meant for emergency situations, that's actually a terrible mistake because at that particular point in time, their investment is mostly vulnerable to any emergencies that may arise after that time, and it's just a matter of time before they start tempering with it when a pressing financial needs arises.
