‘Virtual’ means that it does not exist, but it is assumed to exist. So, ‘virtual currency’ is regarded as a non-existent entity, and the act of trading virtual currency is considered a bubble. However, virtual currency exists as an electromagnetic combination, that is, ‘bits (bytes)’ among the constituent elements of matter, and this bit exists on an atom. It exists in a different form, not non-existent. Therefore, it is real, not virtual. Most of the legendary investors have overlooked this point. Ultimately, the bit depends on the atom. As long as the atom doesn’t die, the bits just exist together. - Joseph’s “just my thoughts”
In business, capital means business funds. A successful entrepreneur often says, "I started my business without any capital". It's partly true, but it's a lie. The entrepreneur just said that capital means only cash. However, all kinds of businesses need to be fundamentally business funds in any even not cash. The entrepreneur didn't count the founder's labor cost. No inputs, no outcomes. The uncounted labor costs are called "alternative costs" or "opportunity costs". This comes from comparative advantage. If the entrepreneur doesn't accept the uncounted labor cost as a debt, the entrepreneur is equivalent to losing the profit due to opportunity costs. Please always remember this. There is no free lunch in this world. - Joseph’s “just my thoughts”
