Some random things I learnt about Bitcoin from Stacker News \ stacker news ~bitcoin

Never knew that validity rollups can be built on Bitcoin so as to improve its scalability and programmability. Read more about it here: https://bitcoinrollups.org/
Robosats crossed the 100 BTC milestone for their all-time volume on their P2P Lightning-native BTC exchange. (https://mobile.twitter.com/kerooke/status/1611505502738911234). Employing the Lightning Network, you can be assured that you won’t be plagued by the typical DEX concern of buying "tainted" coins.
Lightsats (https://lightsats.com ) allow you to tip people. All you have to do is to create a tip and share the link and/or QR code with the recipient. Your recipient will be directed to a Lightsats landing page, in which s/he can click on the LNURLw to open her/his LN network and receive the sats. An alternative is to create a wallet on https://legend.lnbits.com, and install a LNURLw plugin there. This will enable you to create individual QR codes, which you can paste in a Word document and print.
These days, you can get yourself a Ledger and buy Bitcoin directly on it.
If you wish to maintain your privacy while using the Lightning Network, Cashu may be what you need as it protects the identities of custodial wallet users by anonymizing tokens. (https://cashu-wallet.vercel.app)
