Yes, you are right sir. If you do not have funds that you can afford to lose, then you should not invest in Bitcoin. But I think you should start an at-list, otherwise you will never get that fund in your hand. Many of us save in life thinking about the future. Then we can save some percentage of those savings in Bitcoin if we want. I think that rather than having a stable income, you should have the mentality that you are saving some for yourself at the end of the day.
