It is very clear what you are saying because every asset that is considered to have value and is also conceptually good, there will always be supply and demand through the market and it will still be determined by the price. So the price of Bitcoin becomes very important to be seen by those who work as investors and also as traders.
I hope you don't misunderstand what I'm explaining, bitcoin become valuable on demand. The higher the demand that occurs in the market, the higher the price, that is the law of the market for any tradable asset. The value of bitcoin is highly dependent on supply and demand regardless of its initial concept as a currency. It is traders, investors and adopters who keep this asset valuable, so there must be a correlation.
Usually those who don't focus on the price of Bitcoin are the developers of new cryptocurrency products with different concepts, because they basically also really like Bitcoin and also try to build new products in the hope that they can be as valuable and valuable as Bitcoin.
What I mean is, long-term investors or long-term holders are those who are not often in front of the monitor to monitor prices. They don't focus on price or trading because they only target long term results. About altcoin developers, that's a different matter and I don't think they should be a variable in this case.
