Can you earn passive income running a Lightning node?
Routing fees, channels being fraudulently closed, the exposure of nodes to online theft and malicious attacks are a few problems with the Lightning Network.
Routing fees are among the vital Lightning Network problems that are required to transfer payments between channels. However, nodes do not get any reward in return for facilitating payments. Also, fraudulent channel closure, which means one party closes the channel without notifying the other party, leading to offline transaction risk is another issue with the LN.
