you need to have a consistent financial system to continue investing. Because as we all know, Bitcoin is not for short-term investment. It is an opportunity to build a wealth by investing for the long term. There may be many obstacles in front of you while investing for the long term. You have to ignore all those obstacles and continue investing. And during all those obstacles, funds will come in handy. Emergency fund, reserve fund and sufficient cash flow. If you have sufficient cash flow, you will not need any other funds. But if you do not have cash flow, then I think it is very necessary for you to start any fund. It is not only investors who need to use the fund. Anyone can arrange funds for them if they want. A fund will help you meet the needs of your family. The investor does not have to break the invested money before reaching the target.
So if you are an investor, in my opinion, you must have a fund or sufficient cash flow.
The problem is people are too worry if they can not arrange funds with right for the investment. They don't want to try it first and see the result because if they can to do that, they will see if what they do is right or wrong. If that is not work good as they want which mean is wrong, they can search the problem and fix that so they can restart the investment.
If someone can allocate his money for his saving or investment, that mean he can try to keep some amount of his money for other things (in this matter is the investment or saving). Investing in Bitcoin mean we arrange the funds we have and there is no forcing for us about when the time we can invest. We manage that for ourselves because only we will know how our financial situation.
