If you are in twenties or early thirties and remain single, earn $3,000 after tax per month, you will probably save $1,000 if you, let's say, spend $500 to $800 on rental, a guest bedroom in a shared house/apartment, $500 on food, $50 on utilities, $150 on phone/internet bills, $400 on commuting costs or gas/maintainance if you have a used car, $200 on occasional entertainment or others. This $1,000 savings will allow you to invest or place a house down payment when time is ripe. Is this possible based on where you live ?
Maybe that depends on the fiat value of each individual, because that kind of value is really big. For example, in any part of the Asian country, it's too big, 3000$ a month. And if it's here in our country, I might only be able to use $800 a month.
And the 2200$ that will be left for me is for sure that I can keep it and can use it in DCA for bitcoin. And that's all I'll do until the right time comes for the bull run that I'm targeting, which is the price of the bitcoin market. And then I will only sell it when it reaches 100k$ each.
