You are misunderstanding the concept of aggressive buying. You are calling buying at the dip agressive buying which is wrong. An investor can buy bitcoin aggressively with any of the accumulation methods beit DCA, lump sum or buying at the dip. Funds shouldn't be reseeved to buy bitcoin aggressively rather we level setup reserve funds to buy at the dip for a cheaper price. The size of your discretionary income is what will determine your level of aggressiveness. The most important thing is that you don't buy over aggressively.
For example, if an investor discretionary income is $70 and he buys bitcoin every week with $55, he is investing aggressively compared to when that's DCAing with $40. Another investor might choose to buy whimpishly with just $20 from his $70 discretionary income.
I prefer to buy aggressively with DCA when the opportunity comes rather than waiting for the dip to buy aggressively because holding too much fiat till a time that you don't know when to use will not help your bitcoin portfolio grow in a fast pace. Front loading is also a good approach to use to boost your bitcoin portfolio size faster.
Bitcoin accumulation is intentional, either DCA, aggressive buying or Front loading. First of all, any investor must be very observant not to get involved in investing his backup funds and emergency funds either unknowingly or intentionally. This does not matter whether it's the Dip or as at when the fund is available.
Using up your back up funds to place you at the risk of selling off your bitcoin at a loss when emergency comes. Invest Aggressively if you can, but be sure not to tamper with your backup funds.No, I disagree on this your last statement here, I mean the words in your statement I made bold, it's only emergency funds you don't temper with no matter what, because it's stands as a shield against any unforseen emergencies in the future, and it's meant to combat real life emergency that may threatens your holdings, but in the case of back up funds, it's primary duty is to give you that financial leverage to act on some things that may impact your holdings positively, like giving you the leverage to buy aggressively when there is a serious dip in the market.
So what am trying to say is that it's only emergency funds that should not be tempered with unless their is a real life emergency, but in the case of a back up fund's, you can use it to buy aggressively during a dip unlike emergency funds that is not to be tempered with.
