The wrong assumption that is Alby's fault for those closed channels.

For a normal use of LN, I would say that 2-3 private channels are more than enough. Even 2 channels with different peers could do it fine.

But choose the LSP that offer re-leasing the channel period, once it expire. Usually you are buying channels for a certain period. When that period it expire, the LSP is free to close it.

Also take in consideration WHY that channel was closed.
