I believe anyone can explain it in a way they understand it or what it mean to them. Being a good Bitcoiner is understanding many things about Bitcoin and especially the investment aspects and possibility of utilizing it in the best way it was designed for. By investment, you should know that Bitcoin is a two seasons coins, bear and bull which are very significant period for Bitcoin, you also know that Bitcoin is a volatile asset, price can be influenced by economic news and price can dip out of your expectations but doesn't mean that it won't pump again. If you don't know all of that, you can not be a better investor or holder. The right utilization of Bitcoin, is knowing its decentralized nature and respecting it, not like some people that says that there should be a Bitcoin centralized bank.
