first lesson is that bitcoins never leave the BITCOIN network
I don't see where they claimed that bitcoins could leave the network
its the standard stupid claim that bitcoins are on the LN network..
so follow logic instead of the gimmick
1. LN is a different network
2. different network = bitcoins are not on that network..
3. why.. because bitcoins dont leave the bitcoin network..
logic. simple
i got no problem with people advertising that they accept some sub-net/side chain/custodial Mysql balance. but if they pretend they are educators. they need to show they know the differences between using/learning the real bitcoin network. vs the subnets that peg/bridge between blockchains
