For those in the Eurozone (SEPA transactions) there are some great options!
  • GetBittr[https://getbittr.com]: No Kyc. Just send >=€25 to them and they will send BTC to your BTC wallet. No support for xpub's, though. 1.5% fee + on-chain fees.
  • PocketBitcoin[https://pocketbitcoin.com]: No Kyc. Just send >=€25 to them and they will send BTC to your BTC wallet. They do support for xpub's, so better for privacy. 1.5% fee + on-chain fees.
  • Relai[https://relai.app]. No Kyc. Use my promo code for 0.5% discount:REL17326. Total fee is again 1.5%. Too bad you can not "push" payments whenever you feel like it, you have to initiate the buying from the app.
