Adam,

- From your explanation it is evident that fast, cheap bitcoin
transactions are possible. It is encouraging that Bitcoin _can_ indeed
compete with Visa, Paypal, et al. via Layer 2 protocols such as Lightning.

The youtube interview with you and Greg re: Lightning requires some
concentration and I'll have to watch it another couple of times to
better grasp everything that is explained about the protocol and its
interaction with Bitcoin.

Thank you for your considered and informative response, else Raystonn
and I might have gotten in an unnecessary scrap about fees, economics
and what not.

regards,
Venzen Khaosan
