Use the money to buy bitcoin using the dca strategy instead of keeping it to buy when bitcoin is dip, what if bitcoin doesn't dip? That means you won't use it to buy bitcoin?, add it to your Discretionary income instead and increase your bitcoin or even if it dip it may not go to your expected price to buy there is nothing wrong if you still add it your Discretionary income buy bitcoin and still hodl.
There is nothing wrong if an investor decides to have a reserve funds for buying the dips so long as it is not preventing him from the regular dcaing.reserve funds can be used to buy the dips whenever it occurs,since during the dips an investor is offer the opportunity to accumulate bitcoin aggressively if the extra cash is there .so there is nothing wrong if an investor decides to set aside part of his discretionary income as reserves for buying the dip while investing the other using DCA .
Using your reserve funds for accumulating Bitcoin during dip is a good way to go, reserve funds is different from emergency funds, reserve funds can be used to accumulate Bitcoin when there's a dip but emergency funds can't be used for accumulating Bitcoin when there's a dip, for me the main reason i have a reserve funds is so I can use it to accumulate aggressively when ever there's a dip in Bitcoin, some people thinks reserve funds and emergency funds are for same purpose, emergency funds are only for emergency situations like health, accident, house issues like fire out break etc while reserve funds are for situations you feel is needed like buying aggressively during the dip or enlargement of business however you can still decide to use it for emergency situations when you have exhausted your emergency funds.
If you don't have a reserve funds and a dip comes and you start using money meant for paying of bills to accumulate aggressively it will affect you and even lead you to dip hands into your Bitcoin investment later in the future but if you use only your reserve funds to do that it won't affect your finance or your Bitcoin investment.
Reserve funds is not to be used to Accumulate aggressively during the dip it is meant to be kept for emergency or situations that only your emergency funds can't handle that is why it is called reserve funds, when there's a dip the only money you should use to accumulate aggressively is your discretionary income for example if you are accumulating using the DCA strategy and you usually use 50 percent of your discretionary income to accumulate you can now use 80 to 90 percent of your discretionary income to accumulate aggressively however the only time you are allowed to do these is when you have a strong emergency, reserves and float funds the reason for these is so that along the way as you are accumulating aggressively and you get into a financial problem your emergency, reserve and float funds can stand out for you.
