He is not making enough money only by exchanging and custody bitcoins. To grow his revenue he must promote everything that will help him make even more money. Still ENS was for me the best achievement on Ethereum, I would love to see an equivalent on Bitcoin, there was this .btc stuff but it was not really on Bitcoin and using yet another shitcoin if remember well. Anyrhing else? Or shouldnwe use nostr for decentralized, censorship-resistant domain name and easy to read bitcoin address mapping?
