You should not be thinking that Bitcoin has bright future, i want you to understand and believe that with Bitcoin investments your future is ever brighter and should know that buying Bitcoin aggressively depends on your discretionary income because Bitcoin goes along with the future from 4-10years, then from the discretionary income you can decide to increase or buy Bitcoin weekly or monthly.
If the goal is to buy Bitcoin to be stored for a period of time like you said, of course the person must have a steady income so that he can use a little of his salary to be used for buying Bitcoin every month. And I think it will be a little simpler for those who have a fixed monthly salary, but for those who do not have a fixed income every month it will be a little more difficult to make Bitcoin purchases in a more consistent way. Because most people will definitely prioritize their living needs before investing in anything in their lives.
All of that can still be arranged well if we have a mature plan to invest in Bitcoin with the DCA strategy which means we must consistently buy Bitcoin to continue accumulating Bitcoin.
Each of us must be able to manage our finances well so that what we invest in is never disturbed just because of reasons to continue life or the need for money in real life which is very important, therefore we must be able to manage our finances between emergency funds, education funds and also money to support our daily lives, the rest we set aside for investment.
People first need proper management and then decide to do anything, if an investor decides to invest in Bitcoin, then he must first develop a long-term mindset, because without long-term Bitcoin holding, we can never expect anything good from Bitcoin. But none of us can say when we will have to face any situation in the future, unexpected situations are a natural thing, so we can never make a long-term investment plan without arranging an emergency fund. There is no obligation to create an emergency fund in advance, you can start investing first, but you must create an emergency fund within 2-3 months after starting the investment, but the emergency fund can never be ignored.
To buy in the dip and hodl is not an easy something, but to gather the money to amount of BTC your want to buy and hodl is the problem some investors are experiencing, and they need to have the money before thinking on how to buy BTC in the dip and hodl. They can develop Short-time mindset to experience some profit that will make them to test long-tim hodling, and it will make them to see the reason majority of investors like to have the long-time mindset.
Even though you make the emergency money more than 3 years, it will make you not to touch your BTC until the price hit higher before you can sell to earn massive profits from the bull market.
