At some point you have to set certain priorities. You simply can't have all your savings put into Bitcoin. Especially that you have a family and kids and mortgage to pay, and also at this point in our economic life, it is hard not to have some extra cash.

Of course you have to minimize saving in fiat because it is fast losing value but it is still the money that everybody accepts. So in times of emergency, fiat is the one you could easily withdraw. Bitcoin's price goes high and low and you cannot sacrifice selling with a loss because you need cash.

This is my way of doing it.

First of all you could reduce your monthly BTC purchases by 50% for example, in that way you can keep buying BTC but also having some cash ready. Another solution would be to sell part of those BTC every time they go in price, buy them again if and when they go down again, and keep the difference.

No matter how much money we earn at the end of the day how much we spend really matters because many people earn decent salary but they stuck with the lifestyle inflation so they keep spending equal amount what they are earning but we really have to spend less and save as much as we can then we can decide how can we diverse the saved amount that can go for investment purpose.

Yep, I’m going to put some cash savings aside and go at it as hard as I did Bitcoin. We are going to start with a cash goal. And maybe instead of stacking before the price goes up, we can stack before a catastrophe happens. Lol. Thanks to y’all that gave me some perspective and busted my chops a bit. I also need to pay off some debts too. I struggled a bit this month and in hind site, didn’t have to had I done the responsible thing. Thanks again.

So you are receiving a monthly income which means you can very well plan everything out.
Clear all the debts and expenses first and then consider investing into bitcoin and saving for the emergency fund.
Once you have settled your debts and expenses you can take the rest of the amount and invest 50% of it in bitcoin and save 50% of it for the emergency fund.
This way you will be able to manage everything at a better level and not feel guilty about over investing in bitcoin.

it takes skill to control emotion over funds and organise your life.
something purposefuly not taught in school because they dont want people managing funds correctly, they love people getting into debt as thats new business oppertunities for banks/services to make fee's on debt.

you really need to organise yourself to properly calm your emotions and ensure your essential bills are paid first and then only invest your disposable income later.

the way i trained myself was back when i started out years ago(share trading before btc was a thing). if the fiat(money) was to pay for a bill.. pay the damned bill. if the money was to pay for a luxury or fastfood. then invest it... you can always buy new clothes later

my main reminder is fast foods only return is a bowel movement and a toilet flush the next day. and so wasting money on a toilet flush was a bad decision. where as missing a rent payment means your thrown on the streets starving.

its better to be strong in changing your diet to a basic foods, saving money there.. instead of trying to juggle bills by getting into debt.

..
organise your life to pay all bills first. and cut out the luxury/excess food costs.
work out how to have more disposable income by not buying that beer on a saturday or the trip to the beach at the weekend. rather than getting into debt by skipping bills that keep a roof over your head and heat in your room
..

write down all your income. and your outgoings
that means all bills, all luxuries, all spending. and work out what you can actually live without.
EG can you live without netflix for a few months. do you really need new sneakers/shoes/clothes so often. is there cheaper brands of essential food.
yep the foodbill is usually the main cost that you can alter. especially if your wasting some of your income on fast food often. . make a sandwich instead
a $20 pizza or a $1 sandwich. its an easy decision that nets you $19 disposable income to invest
do that 5 days a week and you have your $100 without sacrificing yourself or have any debt fears

some people organise themselves where the had (us min wage of $10/h for 40h) $400 a week,  but live in a lifestyle as if they were on U.S. social security/unemployment payments($250).
that way they would have $150 spare

do not buy ethereum.

ethereum is going to 'detonate' into PoS
this means the underlying cost to mine. is no longer going to be millions of asics PoW mining which is/was over $1k of electric cost. instead its going to be 'staked' and only a couple dollars of cost to sign blocks to create fresh coin. this will cause cheap new coins meaning alot of sell-off cheaply while still profiting. causing a massive price correction down to a new low of only a few dollars of value.

actually it doesn't matter if you collect as many sat as possible at this time, but you should have planned everything in advance and divided your finances so that it is neatly arranged between investments, living costs and unexpected funds, maybe in % maybe only you can share to avoid debt when you need money

Every one of us earns money, but that's not enough to gain some extra gain, to be honest. Proper management of the money is quite important. We always need Liquidity for life, we can't ignore that. So always should keep some USD or any fiat to manage emergency situations. Some funds should hold in the wallet to catch the dip. On the other hand, you may buy some sat regularly after filling your needs from the savings. That's how I try to manage. But sadly when I use my holding funds during the dip, sadly it becomes more dips, and can't take advantage. But that's how I am managing earnings.

While DCA (Dollar-Cost Averaging) may be the suitable method for some investors given that most does not have a big capital to invest everything in one go, you must need to prioritize or allocate the amount that you are willing to invest on without compromising your daily/weekly/monthly obligations.

One thing you also might need to understand is that investments are cash. They are investments in a way that you can actually withdraw or cash them out if the emergency calls for such situation. The beauty about investing into cryptocurrencies is you can always cash them out without the need of going through a complex process, compared to other investment methods.
