How do you personally handle moving larger amounts of Bitcoin between wallets?
https://www.reddit.com/r/Bitcoin/comments/1vb679z/how_do_you_personally_handle_moving_larger/
<!-- SC_OFF -->Curious how you guys here approach sending larger amounts of BTC between your own wallets. Do you split it into smaller transactions? Use a specific type of wallet for the receiving side? Double-check everything multiple times? Or just send it normally and accept the risk?

Should I buy more or hold in HYSA
https://www.reddit.com/r/Bitcoin/comments/1vagnl7/should_i_buy_more_or_hold_in_hysa/
<!-- SC_OFF -->In the next two weeks I’ll receive $8,400 post tax. I’m owed $6,400 in a tax refund I should get next year in the early months. I have 0.1 BTC, and around $2,000 in cash right now. I’m going to Shanghai where I’m not sure how much my spending will be (my apartment is paid for already). Most spending will be restaurants and travel within China. My best estimate is somewhere around $1,000 a month. I’m there for 4 months, so $4k spend. Then I go to south east Asia for backpacking where I’m budgeting around $500-750 a week, though I’m not positive on these numbers. I think I can pull off $500 a week all in, for 17 weeks, so call it $8,500. So to sum it up, I’ll need about $13,000 to spend over the next 10 months or so, before I move back home and have no expenses with a job starting soon after. Counting my tax refund and my income and my current savings plus my bitcoin I have, about $23K. That’s about a $10k cushion. Would any of you buy more bitcoin in this situation? I’m thinking if I resource constrain myself I may be more inclined to just spend less, and if I really need it I could just sell the bitcoin.

I’m in a better state now. It’s not the end of the world, but it’s a lot of fucking money… Little background: The setup was IRA custodian is Solera National Bank, exchange at Swan Bitcoin was used as an Investment Trust, purchase a dedicated hardware wallets: coldcard mk3 from https://store.coinkite.com (https://store.coinkite.com/) May 2021 for this ROTH IRA. Got the wallets, followed all the setup/checks/balances from https://youtu.be/FAYmE5-40PQ?is=wiYMHaS_YGKHjNOY for both wallets, sent a test transaction IRA dedicated hardware wallet (2021). I never setup a 25th Passphrase… REST of the BTC stayed in Swan Exchange. Speaking only on this IRA Wallet: SD card stored with wallet details (paper phrase) in a baggie. Dormant until January 2025. I couldn’t deposit more because of Roth IRA threshold. Come January 2025, been learning more about retirement, BTC, multi-Sig, and heard about a Megaback Door to get more money into a Roth IRA. Was able to get money into Solera, transfer to Swan, and purchase more BTC and withdraw to the same wallet address. No new hardware involved at this point. With newer wallets now, I thought newer tech means more security. Let’s test by buying (3 mk4 - same site. There was still record of my 2021 purchase) new wallets and setup a multi-Sig. (still January 2025) For some reason, when I got the new coldcards, I never did anything with them for all of 2025, I guess I was too lazy/daunting to use the hardware and relearn. Coming to January 2026 now, I decided to use these new cards. I dug out the wallet seed (from 2021) phrase paper. Dusted off one of the mk4, walked into the corner of a room in my house (only myself and partner live in the house), plugged in the cold card into an outlet and typed in the seed written down from 2021 (stored in my dresser). Restored my 2021 onto one of the new wallet 2025. Watched updated BTCSession videos on my phone to set everything up again. I never plugged into a computer, since airgapped was the reason I got the coldcards. I used the same SD Card from 2021 though to export the wallet file from the newly restored coldcard. Import that file into Sparrow (needed to update Sparrow at this point), generated a watch-only wallet QR (to scan for my phone) for Blue Wallet to check frequently. This is where the screenshot is from. Honestly, I haven’t touched the wallet with any transactions/seeds since January 2026. This is definitely the point of failure when I restored the 2021 wallet (now on 2 devices). The other wallet purchased at the same time (2021) is fine… for now… This was the transaction.
https://mempool.space/tx/2fe075cf0ec799f3529ed6a28e0a08b45fe1fc9bd93c3f33bdbc42d5bff4f736 My wallet address is (with all transactions, since it’s gone now…): bc1qldkfrrlylk4s9sdyns9jkaajuzugl0dv5m8fxj My key takeaway now never enter the seed phrase into anything. EVER. Even to restore. Always will generate new and use a 25th passphrase. <!-- SC_ON --> submitted by /u/s1ammage (https://www.reddit.com/user/s1ammage)

<!-- SC_OFF -->In the mid 2010s, Tokyo was home to one of the world’s most active international Bitcoin communities. Developers, entrepreneurs, hackers, and early adopters gathered every week. Some participants went on to lead major global companies and projects, while others built infrastructure that remains important to Bitcoin today. For better or worse, with events including the rise and collapse of Mt. Gox, Tokyo became one of the key cities in Bitcoin’s early history. NOT A MEETUP is an attempt to bring that energy back reimagined for Tokyo in the 2020s. Today, powerful technology companies are becoming increasingly intertwined with governments, finance, and surveillance infrastructure. Technology that was once expected to liberate individuals is often used instead to strengthen large platforms and institutions. Open and decentralized technologies such as Bitcoin and Nostr point in another direction. This event is not only about introducing new technology. It is about returning power to individuals and exploring the ideas, music, art, and independent culture surrounding that goal.

Satoshi Nakamoto’s Cryptography Encyclopedia Discovered - Claim Godfather's of Block Chain - Scott Stornetta & Stuart Haber
https://www.reddit.com/r/Bitcoin/comments/1v9xns4/satoshi_nakamotos_cryptography_encyclopedia/
<!-- SC_OFF -->Stuart Haber and Scott Stornetta are two of the Godfathers behind modern cryptographic timestamping or “Block Chain”. Their contributions to Bitcoin are showcased by three academic works referenced in the Bitcoin Whitepaper References section. These two legends have laid as much of Bitcoin’s groundwork as giants like Adam Back, Wei Dai and Hal Finney. In a recent interview, Stornetta repeated a theory about Satoshi that originated from his colleague, Stuart Haber. The Theory: when talking about Satoshi, “...we’re talking about one person, who was professionally a software engineer, and was really dabbling more with the cryptology as well as with the economic incentives...There’s one thing that I haven't seen anyone analyze, and that is the structure of the (Whitepaper) footnotes.” These suggest Satoshi was a “non-professional cryptologist” who “discovered this thing (Block Chain) by reading about it in the Encyclopedia of Cryptology.” - Scott Stornetta This characterization of Satoshi is not much of a ground breaking take. It is consistent with many others who have suggested that Satoshi was an individual polymath coder, not a group. But the detail about the Whitepaper footnotes and a mysterious book are interesting. What are the clues that relate the structure of the Whitepaper footnotes to this mystery encyclopedia? Has no one looked at this angle involving the Whitepaper footnotes before? The Satoshi Times went down this rabbit hole to see what could be found, and the details are fun. We found that there is an Encyclopedia of Cryptography and Security that was published in 2005 by Henk C. A. van Tilborg via Springer, that matches the description given by Stornetta. This pre-dates Bitcoin (2007-2008), and thus could have been a primary resource used by Satoshi Nakamoto in his invention of Bitcoin.
