Existing economics teaches us that mankind invented the monetary system because barter was inconvenient. Despite having a monetary system, people still felt that even currency issued by it was inconvenient; therefore, economists explain that they created the current credit economy system. However, evidence found by anthropologists contradicts that explanation. In other words, it is argued that the credit transaction system existed before the monetary system, and then the credit system became distrusted for some reason. As a result, the monetary system was created and eventually replaced. Cryptocurrency today is a mathematical algorithm that makes it impossible to forge or alter transaction records. This happened because we don’t trust humans, and in ancient times, there was a more advanced credit transaction system. Don’t be fooled into thinking that the present is more advanced than the past. - Joseph’s “just my thoughts”
A lifetime of tuna is about 10 years. They don't have any muscles to suck the water up and constantly have to be moving their bodies to breathe in the water. So, they can not be sleeping or resting a lifetime of tuna. Even going to sleep, tuna must keep on moving in a sleep-like state until their deaths, if they stop moving, they will be dead soon. According to the attribution, tuna can swim in water at over 100 km/h speed, they need so many other fishes as foods to supply the wasted energy for this fact. The tuna is paid for the huge price of becoming a top-rated predator. But I'm not a top predator, so why do I eat so much? - Joseph’s “just my thoughts”
