Ich freue mich beim Lightning Day des 3. BitcoinForums in Ingolstadt dabei zu sein!
Am 11. Oktober 2025 halte ich einen Vortrag zum Thema:
„Wie kann man Lightning-Zahlungen im Geschäft annehmen? “
Ich zeige, wie einfach Unternehmen Lightning-Zahlungen akzeptieren können – schnell, sicher und ohne komplizierte Integration.

They announced that they want to change the definition of Bitcoin to a 2.1 quadrillion supply and dishonor Satoshi. Not sure what’s supposed to be good about that.

Satoshi gave up everything so we could have a bright future.
If you are supporting purging his name with BIP177, we can’t be friends.

The physical receipt where legally required also requires a certified printer.
Fiat card terminals need the secondary receipt printer so you can see they charged what they said they charged.
Unnecessary with Lightning.

Relatively simple. Apple forces all nfc data from active terminals (even if the terminal explicitly communicates it want to be passively read) to Apple wallet, which doesn’t support Lightning/Bitcoin, yet.
They are forced now to open this up due to lawsuits, so hopefully soon, we will be able to get the full Apple ecosystem onto Lightning.

I’m excited to be hosting a Guided Tour at OMR this year on May 7th at 3:45 PM on the topic:
💸 Digital Cash – The Future of Payments
How will digital currencies and blockchain technology reshape the way we pay and get paid?
From Bitcoin Lightning payments to tokenized company shares and assets on the blockchain — we’ll dive into the tech that's redefining value transfer.
🎟️ Spots are almost fully booked — but you are welcome to drop by and visit us at booth B6 B07.
Looking forward to some great conversations!

Businesses in industries such as hospitality, gastronomy, retail, tourism and others are grappling with rising prices and costs, which inevitably trickle down to the customer. The same holds true for payment methods, where the desire for cashless transactions clashes with high fees associated with card payments.
At OPAGO PAY, we understand these challenges. That's why we offer: a mere 1% Fee for all incoming Bitcoin payments with Instant Payment Settlement. And here's the kicker - no fixed monthly costs! Our pay-per-use model ensures that businesses can thrive without the burden of hefty fees. Additionally, this year, it will be possible to convert these payments directly into Euro and automatically transfer them to your business bank account.
Join us in embracing seamless, cost-effective payment solutions!

Meet Orlando, the owner of the bar Niederlassung in Munich who has started accepting Bitcoin as a payment method via OPAGO PAY as of today. The Niederlassung is centrally located near Viktualienmarkt, making it an excellent choice for after-work drinks or weekend outings.
In addition to cocktails and long drinks, there's also a wide selection of national and international gins available.
What Orlando particularly appreciates is the ability of OPAGO PAY to accept Bitcoin payments in the outdoor area without requiring an internet connection. This is especially useful since the POS-Terminal for card payments in the outdoor area cannot establish a connection.
