There is no reason to wait at all in order to start investing in bitcoin. A person can start right away, as soon as they determine that they have discretionary funds.
Some intending investors are full of excuses even when the have heard that what they actually required to invest with in Bitcoin is their discreationary income, they will still want to tell you that they need to have as stable income before they can invest then you began to ask yourself if stable income is what guarantees them investment in Bitcoin or their discretionary income, some people fail to understand that as long as their is a way you can figure out your discreationary income from any source, you can actually invest in Bitcoin, what some persons lack is understanding, what makes us ready to invest in Bitcoin is our discreationary income, once it is available waiting become invalid and dangerous
Each person has to make the judgment for himself in regards to how much discretionary funds is sufficiently comfortable to get started buying bitcoin, whether that is an extra $100 or an extra $10 or some other amount that allows them to at least get started buying bitcoin. And, then perhaps once they start to buy bitcoin, then it might be easier to decide again to buy some more bitcoin the following week or maybe on a weekly basis.
There can also be circumstances in which guys consider their income situation and even the amount of discretionary funds that they have to not be enough in order to give them confidence to buy bitcoin on a regular basis, yet they still might be able to buy bitcoin once in a while. .which may be enough to get started and better than nothing in terms of potentially planting the roots to regular actions of buying bitcoin, even if the buys might be inconsistent and/or infrequent.
Many of us likely can appreciate a higher comfort level that comes when we have some money coming in every week or two, rather than if we might be in a situation where our work is not very regular, we don't know how long any particular job is going to last and then we may well be uncertain about the next job.. and so in those situations of irregular income and/or irregular expenses, we might lack confidence in either our ability to get started buying bitcoin or our abilities to buy bitcoin on a regular basis.. .and so those guys surely might be in a situation in which they both have to hold higher levels of cash and/or needing to try to figure out ways to increase their income and/or to cut their expenses.

It is not all no-noiner that only come up with the excuses that they don't have discretionary income. The truth is that most of them have a lot of money as discretionary income but what they lack is the basic knowledge to start buying Bitcoin, so based on that they come up with excuses instead they should do some findings that will not take them up to a day to understand properly of what they are doing (if they practice it while learning). So I believe what is keeping some of them back from buying Bitcoin is because they don't have the basic knowledge to start buying Bitcoin. Although someone with common sense can figure it out or probably watch some YouTube videos then understand how to buy Bitcoin through p2p and also figure out the reliable and secured (wallet) way to save their Bitcoin.
Your ideas about "basics of buying" comes off as unclear, even though I understand the idea of how to source the first coins, and there may well be some people who pointed out places to buy bitcoin that would require having a personal wallet, and one of the common starting places tends to be identifying an exchange and then buying through the exchange, which may well be an acceptable place to first get bitcoin and even exposure to the bitcoin price, yet it could be a place that is not very great to hold a lot of value, even though it may be acceptable to hold the first few hundred dollars worth of value while the newbie might be researching into various private ways to hold some (if not all) of his bitcoin. There also might be some legitimate reasons to hold some value on exchanges and to use them regularly for guys who might have not have had identified other ways of getting in and out of bitcoin...and preferably we can find ways to transact with bitcoin or to get in and out of it, since it does seems that going through exchanges can contribute towards issues of locking up coins and/or freezing abilities to get in and out of coins. So, in some sense, with the longer holding of bitcoin, there are likely values in figuring out more than one way to get in and out of coins - even though I agree peer to peer is good and being able to transact with bitcoin is also good.

Emergency funds and reserve funds are among the things that protect and give us a good and progressing investment but we should not prioritize it over our discretionary income because it is what will determine our investment growth.
Your framing of this topic is strange Showlove01, since the back up funds of emergency funds and reserve funds are built from discretionary income, so surely if we have discretionary funds coming in, we have the option to spend from the discretionary funds and then to continue to build up the emergency funds/reserve funds, and surely if the discretionary funds are not sufficient to cover our expenses, then we can tap into any of the back up funds of the emergency funds and/or the reserve funds, and generally the idea of tapping into reserve funds would be easier to do than tapping into emergency funds, since we may well would have had established more limitations on when it is acceptable to tap into emergency funds, and we may well be trying to put systems in place so that we never have to tap into emergency funds absent running out of all other funds and being put in a situation of having no other choice (including considerations to protect our bitcoin stash so we are spending from emergency funds so that we might not have to tap into our bitcoin, unless we also run out of (deplete) our emergency funds, then we might not have any other resources left to tap into besides our bitcoin, which even if we end up having to tap into our bitcoin at a time that is not of our choosing, we might well hope that the various back up funds that we had built might have had allowed us to ONLY tap into our bitcoin in minimal ways rather than greatly depleting our bitcoin after perhaps years and years of building it up. Sometimes if the emergency is so great (and/or long lasting), we might not have any choices but to greatly (if not completely) deplete our various funds within a priority order in which we try to tap into the most valuable of the assets at the latest of times.
However, emergency funds or reserve funds can not actually be measured or determined how far or long it will help us against any unforseen circumstances because as the name implies unforseen circumstances, we can not really tell how challenging it can be but at some point a good investor should estimate how much to reserve.
You are correct about some of the unknowns, yet that each of us has responsibilities to try to be reasonable in how we balance the level of the various back up funds that we have and how we might draw from them (in what order) and any other measures that we might try to take to increase our income and/or to decrease our expenses during times in which our various back up funds might be being depleted... so one thing is preparing for such circumstances and then another thing is dealing with such circumstances of decreased income and/or increased expenses once such unexpected circumstances start to happen.
