Thanks for the info and feedback.

Second, I've heard @rogerkver say a few times that he is happy to support a second layer solution for BCH if and when it is ready.

Cool. So it isn't about never wanting an off-chain layer, but I suppose more just that he wants the built in TPS to be as high as possible.

Firstly, I don't think either BTC or BCH will ever take the whole market. There will be a whole range of coins and tokens used for various transactions.

Why do you think that?

Some people may want privacy, so if Bitcoin doesn't build a way to do that, then maybe Monero wins a little share.

But outside of that, transactions don't usually necessitate that the money has different properties. Whatever is the best way to pay for a tomato should usually be the best way to pay for a bicycle. So people should prefer whichever has the network effect.

It may take a while to settle and reach the long-term conclusion. And always someone somewhere will accept whatever. So technically I imagine you're right in the sense that it won't be 100%. But I think it becomes the brunt of it, over time.

[Meaning, as far as payment/transfer goes. Not disputing that Steem and other blockchains can succeed at doing things outside of payments.]
