Many people think that they have gotten it all just because they hold some amount of Bitcoin, they think it's a get rich quick scheme. Being a good Bitcoiner is beyond just holding Bitcoin.
Bitcoin is Bitcoin and Bitcoiners are Bitcoiners. I don't know there are good Bitcoiners and bad Bitcoiners, to be honest with you. In my opinion, Bitcoiners are people who have bitcoin and hold their bitcoin for a long time with diamond hands and don't shake hands to sell bitcoins in price dips and fud times. That's it.
Other people who are not able to do those things are not Bitcoiners but they're more likely gamblers, traders and speculators. Unfortunately, there are always people like that, and they are parts of Bitcoin community and the market. Bitcoin community and market need both investors, traders, speculators and gamblers to be a live one.
A bitcoiner is one who owns bitcoin, saves it or uses it. Anyhow the person wants to use it doesn't disqualify anyone from being a bitcoiner. I do not believe in the ideology of a good and a bad bitcoiners. Infact, it seems that the ones you see or classified as bad bitcoiners are even the ones sustaining the bitcoin network. When they sell prematurely, they help release the bitcoin to the network and they keep circulating it.
What makes you a good bitcoin is to own a bitcoin, run a node and contribute to the bitcoin network and that's all.
