My OSL Hong Kong account has been mysteriously shut down after only 3 months of opening, with a single BTC trade. I can’t tell if it was because one of my verified wallets gave them concerns, or perhaps because I am American (maybe they changed their policy), or perhaps because they found I am a permanent resident in China? Or maybe they don’t like that I only did 10k HKD and found their service ludicrously expensive. Who knows. It’s quite disappointing to see the state of Hong Kong these days. I also was denied a bank account at ZA due to being American and the HKMA complaint resulted in “oh well.” State of the world.

I have been thoroughly impressed with the CoinJoin plugin inside @npub155m…dcvg. I’m not an expert on it. It has so many configurations possible to run your own coordinator, and I’m a bit lost on knowing the full risks and costs of using other coordinators. I’ve started small, and hope to keep learning as I go.

Keybase had a great way of associating proofs of identity (dns, social media, wallets, etc) to a private key. I wish there was something like that for Nostr clients like Damus so I could start to easily filter spam accounts impersonating other users. Centralization is not always bad, as long as I can toggle the service provider and retain my data without censorship.

While I am happy to now be considered a @npub155m…dcvg code contributor for using my volunteer created rust-teos docker container, I am curious what is the future of The Eye of Satoshi for Lightning? Why is there no official docker container being maintained on docker hub? TEOS seems like a great idea and one that should be encouraged for all Lightning nodes, but I am eager to learn if others recommend another solution.

I’m hopeful that one day bitcoin supports drivechain (bip300/bip301) to allow a real evm compatible layer2 to be supported by Bitcoin.
I’ll keep holding my Ethereum, but I think Bitcoin can address its long term miner incentivized security concerns by enabling this type of capability.

I love how the WSJ still considers the halving merely a theory, and that the only reason people are buying bitcoin is because of ETFs. While the article is well written, they would have a more accurate perspective if they left Wall Street more often and studied the space a little closer.

Exactly as others said… it’s the BIP39 seed phrase (and optional BIP38 passphrase) that are the REAL security. The hardware wallet is a convenient way to avoid having to touch these while signing a transaction. I recommend using metal stored in a secure location(s) for your seed phrase — never online (even encrypted, it’s too scary for me!)
