Low income earners who do barely have enough to feed exist but in such situation, investing in Bitcoin is the last thing they should worry about because they need money to invest in Bitcoin. If they use the money they are supposed to use for feeding and invest in Bitcoin, it is a matter of days or week before they sell the Bitcoin because food is a basic necessity unless they have decided that they will die of hunger instead of selling their Bitcoin so that when they die someone else will sell the Bitcoin or it becomes lost coins.
To invest in Bitcoin and be able to HODL it, the investor must first of all set up the money for their basic needs which cover food, shelter, medical and others. After then the investor have to protect the investment by setting up emergency funds that will take care of things that fall outside the basic needs which can come up unplanned. It is after this two set of funds are in place that there will be some level of confidence that the investor can invest in Bitcoin and HODL without the pressure to sell.
Your right. Some persons shouldn't worry about starting an investment until they are capable of sustaining it. There are thins that are criteria to secure an investment ongoing on. One is to have enough to take care of monthly needs, if we have a family then the family first before thinking of investing. Expenses as rent, tuition fees, and emergencies fund should be met first before proceeding with the investment. When i hear people using money that was meant for this important life needs to invest in Bitcoin i feel sorry because it doesn't take them long they sell off the investment in the short term with little profit. As an investor i think it is good we ask our self what is the vision we have for our investment, if we are in for short or long term because a successful Bitcoin investment is determined by the level of discipline, consistency and sustainability of effort an investor put into it in the long term.
If the family is totally dependent on my income then we can think of investing with the remaining amount of money after meeting the needs of the family first. No one will advise you to invest without family. However, if properly planned, one can fulfill one's dream by investing in one's own investment, even if one earns relatively less money but meets the needs of the family. In order to invest, the investor must first be interested enough in his investment and give a lot of importance to the matter. When the matter is given a lot of importance by the investors, they will be able to maintain the continuity of investment consistently.
Those who dream that Bitcoin will one day cross $100k are trying to invest in a long-term plan anyway. If they keep on trying like this then in time they will definitely succeed and the expectations they have invested in will be fulfilled.
