These discussions could potentially lead to good ideas.
One idea that i could think is determine block size limit based on hardware/internet growth. There's one BIP about it which is, BIP 103 Block size following technological growth (
https://github.com/bitcoin/bips/blob/master/bip-0103.mediawiki).
The hard part are,
1. Determine the proper percentage for block size limit growth. The BIP mention 17.7% growth/year.
2. Until when the the limit growth happen? The BIP mention until July 2063, but i doubt today's growth will reflect growth in next 42 years.
Doge can move small and medium sums faster and cheaper and safely.
Minus the fact you're using multiple coins at once and need to find service which accept it. LN isn't perfect, but could be better option if you regularly make micro-transaction.
