I'm one of the founders of Lightsats 😃

It's extremely easy and I would encourage you to test it out or if you'd like I can send you a link to a tip via Twitter or something to make sure only you can claim it.

You can authenticate via your Lightning Wallet (Breez, BlueWallet, Phoenix, Zeus, Blixt or Alby on a desktop) then you select the amount you want to tip/gift, fund the invoice and it will automatically generate a QR code the receiver can scan or you can copy and send the link via sms or post it anywhere just like the one below from @Jimbo.

For a brand new user they go through this onboarding, where we give them a brief introduction to what bitcoin is and a Lightning wallet recommendation page so they can download their first wallet and withdraw their sats to their custody. https://lightsats.com/journey/bitcoin

If the user claims their sats but do not withdraw them before an expiry date you set the tip to then you can reclaim them back to your custody.

Also we are starting to add this bitcoin guide so users can start exploring https://lightsats.com/guide
