Makes sense. If everyone were the same, the market would just freeze without any trading going on. It's indeed important to have both buyers and sellers, but I disagree buyers are necessarily bullish while sellers are bearish. If we look at Bitcoin not as an investment opportunity, but as money, people should be focused on exchanging goods and services via Bitcoin, thus buying and selling it regardless of beliefs in its future but just largely being neutral about it. So one way of balancing is when bullish people are in balance with bearish people, but another option is when everyone is neutral (simply believing that Bitcoin will be around and will have more or less the same purchasing power). I do agree that with the current rate of adoption and the ways Bitcoin is mainly used the neutral way is very hypothetical.
