Time preference question: Suppose you sent bitcoins to a timelocked address (made with OP_CLTV). How many years/decades would the bitcoins have to be locked up for so that to you personally it's the same thing as just destroying them?

Making the case for flag day activation of taproot lists.linuxfoundation.org/pi… BIP8 activation is dead, as we can't agree on the value of LOT. We need something else.

The "users first", permissionless types who prefer LOT=true will like that flag day activation takes activation out of the hands of miners

The "safe, secure and conservative" approach which prefers LOT=false can be made happy with a number of derisking methods (see the email)

“Bitcoin could have coded your name or IP into every transaction. It didn't. The whitepaper even has a section on privacy. It's incorrect to say that Bitcoin isn't focused on privacy. Sufficient privacy is an essential prerequisite for a viable digital currency” -@chris_belcher_
/u/belcher_: That's a good question. Financial privacy is an essential element to fungibility in Bitcoin: if you can meaningfully distinguish one coin from another, then their fun reddit.com/r/Bitcoin/comment…

.@chris_belcher_ took to the bitcoin-dev mailing list to announce progress on his CoinSwap implementation. Check out Teleport Transactions. Support the cause. And get us closer to borking chain analysis heuristics that reduce the privacy of bitcoiners. tftc.io/martys-bent/issue-93…

I always advice against BIP39 for this reason. There's currently a guy in the electrum IRC channel asking for help with his seed that he made years ago.
BIP39 has a beautiful way to screw users: when users do not remember which software was used to create their seed, and they fail to recover their balance because of that, then they will never know for sure whether that seed had a balance at all...

nitter.net/stephanlivera/st… In this podcast @mflaxman mentions how one reason he thinks Electrum isn't that great is because it doesnt create BIP39 seeds (only recovers them), but for this reason we see that's actually a benefit
