I think I get it now. Thank you.
1. Buy Bitcoin on lighting using robosats.
2. Exchange lightning to liquid on boltz and send liquid to green wallet.
3. After a while, when it adds up and once fees are lower, peg out from liquid to Bitcoin on-chain, using sideswap and send to cold storage.
Am I getting it right? Like a plan for stacking sats with privacy and low fees?
