The reason why during inflation is not a time to relax from investing is that when one invests, you are making a good plan for the future; but if you wait to get a good income, there is a possibility that you will not invest.
All you said is quite understandable bro. The point is that not having a good or huge source of income shouldn't be the reason or what will completely stop us from investing in bitcoin, because we can actually initiate an investment plan with the little we're earning no doubt if only we can be able to figure out our discretionary funds from it everything will be nice. Moreover bitcoin investment has made it very open for even the average Nigerians or persons to invest using the dca method which is the most conducive strategy to go with.
Furthermore, as much as I know the only reason that can stop someone from investing in bitcoin is lack of interest and nothing more. Otherwise I hate hearing things like low income rate , zero knowledge about Bitcoin investment and so on.
