Guys, don't get fooled both by the current prices and future predictions good or bad. Bitcoin alone obviously cannot carry the entire crypto payment industry [LN or not]. The competition against Bitcoin is ongoing and is getting only stronger. Watch this space!
How to add a Trezor wallet to Bitcoin Core as watch-only
I wanted to use Bitcoin Core to keep an eye on transactions (basically using your own full Bitcoin node to validate, instead of "trusting" Satoshilabs and their webwallet). This doesn't mean there's anything wrong with Satoshilabls' trezor web wallet - it's just a matter of being totally sovereign/independent - if you want that, then using your own Bitcoin Core full node is a must. Spent some time investigating how to do that, so sharing here in case someone wants it. Feel free to point any ways to do it better. How-To:
Convert the ypub to xpub using something like this: https://jlopp.github.io/xpub-converte You can save the page and run it offline/airgapped in something like Tails if you don't trust it. There is no security risk (not a private key) but only privacy risk (with your public keys the site can see all transactions/balances of that wallet)
Then open Bitcoin Core and do these other steps...
In File>Create Wallet, create a wallet with "No Encryption" & "Watch Only" - call it anything you like (TrezorA for example).
Open Window>Console, select the wallet you just created (on the pull-down menu at the top) and then paste the importmulti command where you put your xpub.
Core will complain that the checksum is wrong (the "7x87wdy3" and "wdxy2s2t" parts in my example) replace them with the right ones shown in the message and retry.
You should see the wallet imported with success, but with no transaction history. It is necessary to rescan the chain to index the transactions that wallet made. To save time, you can use the blockheight of the first block where you made a transaction with that trezor, for example: "rescanblockchain 590500".
You can find out the block by putting the hash of your first transfer in a block explorer like https://live.blockcypher.com/, look for "blockheight" If you have no idea which block has your first transaction, you can just rescan the whole chain by typing "rescanblockchain 0" in the console (but Core will take way longer to do it). That's about it, all transactions made from what wallet should then appear in Core and it will warn every time funds are received or spent. You can be running your own full node and constantly monitoring your wallet, without having to use the Trezor or load Satoshilab's site. You cannot spend from that wallet in Core, but you can use it to generate receive addresses and send to it (keep in mind that if you generate bech32 addresses in Core, those transfers will not appear at Trezor wallet since it doesn't support it yet :| ) Edit: Forgot change addresses, fixed importmulti example.
Ledger Nano X + Ledger Live iOS + watch-only bitcoin core full node?
I'm not a blockchain expert. Question is this: Is the combination of 1. using Ledger Nano X for cool storage, 2. using ledger live iOS app for making transactions, and 3. using a bitcoin core full node with master pubkey for reliable verification of transactions... is that a secure method of using and storing bitcoins that also supports the decentralization of the network? Does that lack any essential functionality? Any major security risks?

Finally back to the original path after all of that bullshit. It feels like it’s been a decade. Only 5 years for me. Was banned from bitcoin reddit ages back. Finally I feel like I can return. Just watch T2 again last night and this felt like the right sentiment:
Live Coin Watch is a cryptocurrency news site covering Bitcoin (BTC), Ethereum (ETH), altcoins, ICOs, and blockchain technology. Address: 2035 Sunset Lake Road, Suite B-2 Newark, DE 19702 Phone Number: 914-482-1290 Bitcoin was originally invented by an unknown person or group under the pseudonym Satoshi Nakamoto and released as open-source software in 2009. Bitcoin has long been the face of cryptocurrency, and research produced by the University of Cambridge estimates that in 2017, there are 2.9 to 5.8 million unique users using a cryptocurrency wallet Step 10: Your Bitcoin watch only wallet is created. Your Bitcoin watch only wallet has been created. Just a few more steps to go! Verify that your wallet works. Step 11: Check that the balance in your watch only wallet is correct. If you have not transferred funds to the addresses, send some funds to them. A watch-only wallet, as the name suggests it is just a Bitcoin wallet that is used for watching only. A watch only address doesn’t have private keys and you’ll not be able to spend any Bitcoins associated with that address. While the watch serves not only its purpose of telling time but also acts as a gateway to accessing the millennial gold of this era. It is truly an impressive and remarkable creation.
