When you run a lightning node that routes lightning ⚡ payments, you'd earn the fees. However, this means that you have to invest time and money to open large enough ⚡channels and keep them working.
What I've learned:
Bitcoin Node (Knots or Core)
- Your private connection to the bitcoin network
- Very important to keep bitcoin decentralized, the more nodes the better (same for mining ⛏️ even a nerdminer)
Lightning ⚡ node
- Second layer for smaller payments with very small fees
- Instead of paying "high" fees for several on chain transactions, you make one bigger transaction to the lightning ⚡ network
It's worth to study study study and try it out with small amounts. We the people shape our future with sovereignty.
