Why do I have all my money in Bitcoin? It would be far easier to keep it in my local currency and invest in funds instead.
I choose Bitcoin because I no longer want to participate in the fiat system, where a few enrich themselves at the expense of the many.
That is why I don’t just hold Bitcoin, but also run a node, mine Bitcoin with my “space heaters,” and operate a Lightning node for transactions and routing for others.
I do this to contribute to a decentralized system that no one owns.
