The advantage of Bitcoin's decentralization is that it is not subject to third-party intervention and basically frees itself from government control. Let people actually manage their assets.
At the same time, Bitcoin, as a store of value, also increases investors' income, and many people have truly realized the freedom of wealth through Bitcoin.
The most important thing is that Bitcoin has no discrimination and integrates all countries in the world.
I loved what you said that Bitcoin doesn't discriminate and integrates all nations across the globe, in short it is a global currency which is not controlled by any central bank and its price is determined by the market. Though it is very volatile currency but that is its beauty because it provides opportunity to make profit by using trading skills. Volatility is a gift if you have the expertise to manage the risk.
Although bitcoin can be used as a cross-border money transfer method without third-party intervention. But given its volatility, I still consider it an asset rather than a currency because currencies don't move much, in my opinion.
There is one thing I agree with you on, bitcoin's volatility is one of its beauties. I believe we are all here for the volatility of bitcoin, if bitcoin is not volatile, it cannot be profitable for everyone, and people will not look to bitcoin anymore. So I hope bitcoin will never be stable.
