Here's how I perceive difficulty of activities in Bitcoin:
1 easy -- 10 tough
1 on chain hot wallet
1 lightning hot wallet lightning (custody)
2 custodied sats (exchanges, etc)
2 single sig cold storage
2 running Bitcoin core
3 lightning self custody hot wallet (mutiny, new Zeus, Phoenix)
4 buying no kyc
4 dedicated node (umbrel etc with no lightning)
4 multi sig cold storage
4 shared custody multi sig (unchained)
7 node with lightning and channel management
how would you add or change this
