Most people in Africa are struggling to own bitcoin, taking risks just to own bitcoin, because if you check the living conditions of masses, you will see the main reason why there is many adoption of bitcoin especially by their young citizens is because bitcoin is hope. Bitcoin has become the shinning light they can look up to for a brighter future and better everything around them, and improve their living conditions. People living below $50 monthly salary are still buying bitcoin and hodling for dear life.
Isn't it better for people like that who have a salary below $50 to collect money first before buying BTC. Or at least it is better to invest in trading with a short term. And if there is more profit from trading can be saved to meet the target, if you feel the target has been reached you will be ready to start long-term investment by buying BTC with the DCA method. Because if you push too hard it will be very risky, better slowly but surely,
Having such low income could become a big hindrance to buying bitcoin especially for older persons with more expenses and even trying to reduce expense to invest might not even be a good idea cause you also need to consider having an emergency fund and the income would not be able to cater for both,
Trading is still not the best option considering the time it would take to learn and master the skill, the best option for such persons would be to find extra sources of Income to be able to buy bitcoin and have more discretionary income to spare to buying bitcoin, why i recommend this is cause its the safest option that doesn't involve having to risk the income you have.
While Im not trying to say that a person earning 50$ weekly cannot invest in bitcoin, the point is that you can't invest in bitcoin or its not advisable to invest in bitcoin if your income is not enough to cater for your expense and emergency funds or savings, the best option would be to increase your income.
