Having fun while investing in Bitcoin is not a bad thing per say but the fun one is having should be within the reach of the person, the fun should not affect the person's investment otherwise it becomes a bad thing. A wise investor should know how to have his or her fun I mean there should be a limit to every fun one wants to get and I doubt if a normal person will use his or her investment money to have fun I mean it shows a level of unseriousness and stupidity. Anyone who can not invest when they have a little money can not be able to invest even if they have a huge amount of money.
It is not important to have a little money or a lot of money to invest. You have to keep an eye on whether you have prudent money to invest. There are many people who have a lot of money but it is not prudent or unnecessary money to invest. It is better for such a person not to invest and to start investing, it is better to try to be prudent in the source of income and be associated with Bitcoin. Again, you will see some people who have little money but it is prudent or unnecessary money to invest. That is, your income is high or you have a lot of money does not mean that you can invest, your spending on your income will determine whether you are eligible for investment or not.
Even if you have a strong desire to invest, you should reconsider your expenses and reduce unnecessary expenses. In this case, you should have at least basic knowledge about financial management and be educated about financial management. If you are educated in financial management, it will be possible for you to identify unwanted expenses and reduce them. Money can be spent on fun but in a limited or disciplined manner. Select the money to meet your daily needs for investment, then set aside money for investment. If there is no money left for investment after meeting the needs, then you can look for alternative sources of income or work to improve your source of income.
