I agree with you that investors need to have source of income before they can approach the market to buy bitcoin in the dip which is a good idea,
You don't need to wait fod the dip before you can buy bitcoin mate, that's a wrong approach towards building a strong bitcoin portfolio for your future because you will only be buying once in a while and that's not even certain because what if the dip did not come. You will keep on waiting till infinity and miss out the chance of building and growing your bitcoin portfolio gradually overtime through DCA method which allows you to ignore the market price and stack up more sats with consistent and persistent for 4-10 years and above till you reach your bitcoin target.
Anyone waiting to buy bitcoin at the dip wouldn't have a target because he is not serious and focused in building his bitcoin portfolio as fast as possible with his discretionary income rather he prefers to buy at a very cheap price and will end up as a low coiner in the future. Such investors will definitely regret their actions for not accumulating as many bitcoin as possible when they have the money to do so.
make sure you use what you can afford to lose in bitcoin whenever you want to buy bitcoin and it will help you to focus on a long holding that will make you to earn good income from your holding, bitcoin is different from other business you can start today and start seeing instant result because there are some bearish season you will encounter in the process of holding bitcoin without be move to release your bitcoin no matter the challenge surrounding you because you have other source of income you can use to solve those challenges, but if you don't have such sources of income you will not overcome such challenges, this is the reason why is good to have source of income before going into long term holding.
I don't understand the kind of result that you are talking about because bitcoin investment that I know will take a pleb a complete circle before he can see a significant increase in his bitcoin portfolio if he keeps his DCA ongoing with consistent and persistent. Bitcoin is not a get rich quick scheme and you should know how you are talking an out bitcoin so that you don't mislead people that they can start making profits immediately the invest.
You can invest today and bitcoin price dips with 20% the next day, what will you say about that. Profits shouldn't be your concern as a new investor but staying focused on accumulating and hodli your bitcoin till you reach your target should be your priority.
