I think with trading they will be a provision of food in our table, when we understand the rules and regulations of Bitcoin, I don't know if this my concept can make a provision of food through Bitcoin. But I'm well convinced that with this my views over Bitcoin investment and trading it will provide or sustain human, if profit are been made. I know that Bitcoin should not be dependent on, and we suppose to make Bitcoin our side hustle but with seriousness on Bitcoin investment and trading, we can achieve a success.
It could be not like that even if you learn it. Because in trading, there are sellers and buyers in one system, in this case, there will be advantages and disadvantages if there is a trade. So if there are food in your table, on the other hand, there is an empty table for people who have suffered a loss. So, you also have to think about humanity on how to minimalizing empty food on other people. We certainly hope everyone who invests in Bitcoin will get a profit but in fact, not all people (100%) got the benefit, there will definitely be a loss where buying your bitcoin on ATH.
The point is, you cannot rely solely on Bitcoin for your annual budget, especially for food. It is unstable and too much of a risk to do. As you stated, not everyone can get profit, at most not the same amount, and with inflation still around and being heavily felt by the majority of the world, it is very risky and wreckless to depend on Bitcoin for food budgets. Because imagine this, you rely on Bitcoin to provide money for your daily food and something tragic happens and you are not able to gain profit, the exchange became too low and it is not enough to buy food for everyone in your family, what happens next? Where will you get food?
