If we're talking specifically about speculative investors only, then your words hold true. Most markets aren't driven by a zero-sum game like you're illustrating here. They are a function of value creation and the exchange of that created value. In these kinds of value-creating exchanges, more wealth exists in the world after the transaction is completed. I think what we're seeing in the BTC trades now is a residual effect of the extreme levels of value that BTC brought to the table in the first place. We haven't reached saturation yet, so the zero sum game hasn't started yet, in which BTC becomes just a simple ledger and a great store of value.
