Another vote for Green, I see. Good to know. Will keep an eye on it re. LN integration.

Yes, the on-chain fee size is becoming an issue for small payments. But then again, buying coffee on-chain is like using a chainsaw to cut butter. So yeah, 2nd-layer BTC networks are important, and will be more so in the future. I know (have been reading here and there, and also in WO) that LN has its problems, but I hope they get ironed out and we end up with a robust 2nd-layer network, with the uptime and reliability of on-chain transactions, that's going to be standardized and adopted worldwide as a payment method. Michael Saylor is actively promoting this IIRC, as is Jack Dorsey and other big players out there. And no, LTC won't cut it, as it is just a matter of time (i.e., network load) before it clogs up too. The solution must be by design, not by low utilization.
