You need to save up some money that will be sufficient for the investment, and if you look at the people who hold coins today, a lot of them invest with their savings funds. Saving money is also another way to invest in bitcoin.
I highly agree with you, most of those who saved money are now big Bitcoin investors. The ones who found out about Bitcoin started investing money on it after saving a certain amount for sometime. Those are known as DIP buyers, they always looked for good dips and then they accumulated Bitcoin during those dips. They never invested their monthly salaries or followed a DCA method, they just invested the money they have saved for the sake of investing, and trust me most of them are financially stable now.
I personally know someone who saved money and waited for bear market, and when bear market for intensity that person invested the money into some altcoins which have gained more than 2x to 4x value for him even in start of the bull run. So that's why I believe saving is the best way for those who are thinking about investing in crypto currencies, and such people will always get some good profits in the end if they invest their savings in good projects, especially those who invest in Bitcoin will end up with good profits.
Saving is good but you can only grow your finances VERY SLOW process and doesn’t give you any significant personal growth by the next 10 years.
A main his 20s made that mistake of just saving...
At 2020 when the covid is happening, the market crash and he got no money left to participate in the momentum because his job was the only source of his income.
Having a lot of time alone at home with nothing to do, he thought about it and decided to take action ASAP.
He deep dive into digital marketing and start my online business selling clothes, flowers, real estate, shoes, etc.
To cut the story short, he earn 5 times of the net worth in the recent years he now took most of his earnings and invested in bitcoin after 2021 and the last 3 years today's he has become a millionaire just through investing the bitcoin with the little he had that's power of investment so I urge all of us to cultivate the habit of investment no matter anything........
Aside from that, he also believe that he change a lot as a person by having much more confidence and power to help those in needs around him then till also now...
So I can say that Having a massive income and then investing dilligently to stay rich is the better way to me....
