For the vast majority of folks, income, cashflow and expenses are likely mostly denominated in fiat.. so if we want to try to create a decent amount of stability in our own lives in terms of finances and psychology, we need to keep a certain amount of value within the unit that we are expecting to be paying expenses on a regular basis, and surely 3 months would be a minimum that we should be projecting out our cashflow, but preferably we should have good ideas for our cashflow 6-24 months into the future with greater degrees of certainty on shorter periods, and it can take a decently long time to get systems in place in order to be able to project out cashflows, and surely the less complicated our cashflows, the less need to project out or even to keep a cushion (including various emergency funds).
Everyone has to determine cash inflows and outflows, this stability must really be feasible which is projected to support daily needs using fiat, as long as the process goes on for months and after everything is stable, then people can place investment standards in bitcoin, for me there are simple steps to get us involved consistently in bitcoin investing by creating a balanced cash flow pattern. For example, for every 100% accumulative income, 50% is used for daily needs, 20% for savings and 30% for investment, thus the calculations carried out will revive three important sectors and not ignore basic responsibilities as fulfillment. The percentage of the amount of money collected is in accordance with the income of each individual and it is not cumulatively the same.
Your numbers are quite unusual, and also your way of specifying your numbers is kind of vague and even potentially misleading/confusing.
I would suggest that the vast majority of folks are not in a situation in which they can save/invest 50% of their income, so if you have that much ability to save/invest you are in a very strong financial position. Now if you are in some kind of a sheltered situation in which many of your lodging and food expenses are covered, then maybe that could be a temporary situation - or surely it is possible to find some kinds of living arrangements that are not toiling in terms of the amounts if the cost of the location is being shared. For many years, I used to sublet out portions of my living space, which caused my own living expenses to be way lower than other similarly-situated people of my then income level.
There are a lot of ways to classify out the ways that you use your cashflow, and I would surmise that the category of having a savings is merely a way of having a float in which that money could be used towards investing or used towards expenses depending on how much of a float that you want to maintain, and many people do have trouble even allocating more than 10% of their income towards investing.. even though it is healthy to have 10% to 20% (or more if possible) that can be invested on a regular basis.. perhaps keeping track monthly cashflow/expenses and then at least projecting out 3-6 months or maybe even projecting out up to 24 months is good.. with most of the focus being on making sure that the 3-6 months is pretty well understood and so the further out periods can be more vague and ballpark ideas, but still there should be abilities to identify if there might be some cashflow crunches that might happen 1 year or 2 years out based on information already largely known.
I doubt that long lead times necessarily create insurmountable obstacles in regards to whether transactions can (should or would be preferable to) be made in bitcoin, even if the transaction amounts might be denominated in dollars and then ultimately the value sent in bitcoin.
Of course, the value of the transaction should be agreed at the time that it is sent, and perhaps even the method of sending needs to be agreed to and an agreement regarding who pays the fees, yet none of these considerations should necessarily be considered as insurmountable obstacles, and there are likely ways in which both parties would be able to benefit by transacting in bitcoin.
Of course, it is up to each party to calculate whether they prefer to transact in bitcoin or if they want to use dollars or some other transaction medium, and there should be a presumption that the parties are ONLY going to transact in bitcoin if each of them independently perceive that it is either in their benefit to transact in bitcoin or that the costs of transacting in bitcoin do not outweigh the benefits (or potential benefits if all of the benefits might not be known at the time of the transaction).
Most likely, these points can be taken into account by the parties, for example, payment can be made in bitcoin but at the rate on the day of payment, so that the parties receive exactly the amount that was prescribed in the contract. When the company works with payment in bitcoin, then over time all these points can be worked out, experience will appear and it will be possible to take into account a number of points that may affect one of the parties.
I question why you are so inclined to include periods of uncertainty, as if the deal needs to be renegotiated at various points in time, when it does not. The parties likely have already agreed from the point in which the sale was made about the various terms to such a level that they don't need to agree to hardly shit.. the job is finished and delivered and no more negotiation is needed or even preferred - absent one of the parties not delivering on one end or the other... but that has nothing to do with using bitcoin as a transaction mechanism, but instead disputes that can arise in any business arrangement regarding quality of product/services... no additional dispute needs to be present merely because of volatility if they terms of payment had already been agree to..
Maybe we can discuss this in terms of some kind of a hypothetical. Let's say that one of the parties makes customized beds, so the two parties agreed that there would be a purchase of 10 beds, that need to be delivered one month after the agreement, and the buyer agreed to buy the beds for $1k each, and he will sell them for $2k each. The seller/builder of the beds requires 50% down that is paid upon the date of the sale (signing of a sales contract), and then the remainder of payment upon delivery (or there could be other payment terms, but let's make this simple). The buyer pays $5k down payment using bitcoin at the time of the sale, and no problem right? They agree to how the payment is going to be made, and who is going to cover the fees.
And then one month later, the 10 beds are delivered, and the buyer needs to pay for the beds right, and they already agreed that he was going to be paid in bitcoin. They could have agreed to a bitcoin value, but more likely they would have agreed to a dollar value that is then converted to bitcoin so that the buyer will know how much to pay at the time of the delivery which is exactly equal to $5k plus whatever other ways that they had already agreed to any fees or who would pay the fees or whatever. Where's the complications? Sure the BTC price might have changed, but so what, the contract is denominated in dollars and the method of payment is agreed to be bitcoin... They figure out the amount to send right then, and they might have already specified that they use the fees that are depicted in the app or wallet that they use or maybe they agree to use the Bitstamp exchange rate for the time of payment.
Now if the BTC price is moving around a lot at exactly the time of payment, they could agree to wait and to pay 24 hours later, or they could agree to take an average of the price over the past 12 hours or 24 hours.. and those parameters could be worked out in advance, or maybe if the beds are already delivered then the seller does not want to be fucking around with payments because he already did his part and he delivered the beds.
Payment in bitcoins will only be used if it is beneficial to both parties, if everyone can appreciate the benefits of it. This can be beneficial due to low fees, but may incur significant costs to convert it to fiat. All these points must be taken into account in order to evaluate the benefit.
Each person assesses on their own, so if the buyer does not want to use bitcoin to pay, and if the seller ONLY takes bitcoin, then they are not going to reach an agreement. The same is true if the seller chooses not to take bitcoin, but if all of his competitors are taking bitcoin, but he is not, then if the buyer says that they want to buy in bitcoin, then the seller would need to convince the buyer to change his/her mind or perhaps to show something about his product/service that causes the buyer to want to change his/her preferred method of payment... Sometimes people have options to change their method of payment and sometimes they don't. Sometimes people have options to change their method of payment, but they choose not to change their method of payment for a variety of reasons, including just maybe that they might find it difficult to set up and to get used to - including that even within the decision to start to accept bitcoin as a means of payment, the ways that it is set up or the processes might get easier.. but at the same time, there can be some reluctance to learn how to set it up or to make changes each time, and even if the system is set up, there can be some questions about whether it is secured and backed up, so even if it is working, there can be worries about holding a lot of value on a hot wallet or even needing to monitor that the price is going up or down, so it can take time to put systems in place in order to feel that there are not needs to monitor the price changes on an hourly basis.. and maybe just once a week or so... or once a quarter.
