Balancing your financial security is a good thing while investing in Bitcoin because investing in any business whether in crypto or any other business without giving much attention to saving is no a good practice as it will affect your financial stability and emergency fund should be as a matter of fact be compulsory for any individual who is ready to investing in Bitcoin because there are other things that will also need finance so putting all your money inyo Bitcoin accumulation will be harmful because Bitcoin investment is focused on a long term basis
It is clear from your quote that you are not yet familiar with the basic knowledge of Bitcoin investment. Here I will not blame you, but rather suggest you to gain basic knowledge about investment.
Basic knowledge of investment means that you should invest only the amount of money that you can afford to lose. That is, suppose your monthly income is $1000 and your daily expenses are $700. Now the remaining $300 that you have after meeting your daily needs can be called discretionary money which is not very necessary for you. Now you have to find money from that $300 that you can throw away or burn. I am not saying that you should throw it away, rather you should have the mindset of losing that money so that you do not need that money for a long time.
You have to choose the money to invest depending on your situation. Of course, it should be money that is beyond your needs and that you can lose. You have said a bit that investing without focusing on savings is not a good habit. The basic knowledge of investing is to invest with unnecessary money and keep backup funds ready.
I have a thread about the basic knowledge of investing, you can read it if you want. And if you want to read the details of it, you can search AI or Google about the use of points.
Long-Term Investment.
