Fees are less than a penny. System works great, like Bitcoin used to.
Block size as much as makes sense, optimizations where possible, if lightning works (it won't) - use it.
Gavin Andresen has published about his latest work 'Graphene' which shrinks block sizes dramatically.
They'll take/use any good ideas so long as it doesn't cripple basic onchain functionality.
Blocksize and fees are a tradeoff.
1 cent fees are a significant advantage over 20$ fees.
But 0.0001 cent fees aren't really that much more useful for your coffee transactions.
Sure, maybe someone will come up with another chain that is used for true micro transactions.
But what we are saying is, that each of these fee levels are good for different use cases.
Bitcoin's high fees and high security are great for a digital gold product that isn't traded much.
Bitcoin Cash made a different tradeoff in the attempt to go after the daily spending market.
Pros and cons.
Thinking the world will flock to a fixed pool of frictionless digital exchange does not seem insane to me. I'm talking about the ones you can transact for less than a penny (BCH), not the old guard (BTC).
