When we call DollarBit Bitcoin 3.0, we say that DollarBit is the new iteration of Bitcoin that takes into account the latest technological advancement. If versions 4.0, 5.0, etc come out later, then it's all the better for the cryptocurrency community. Improvement, development, advancement, are always better than regressions, stagnation, orthodoxy, and are necessary for the long-term.
