I've one ticket for sale (€190-255), since I bought two tickets (one € 255 supporter for myself and € 190 for partner) but also got a speaker ticket (https://fahrplan.events.ccc.de/congress/2025/fahrplan/event/...), since speaker announcement was after the first round of sales via vouchers.

So let me know if someone is interested in this ticket, see my GitHub for mail address. I know other speakers where even unaware of this (so I might know another ticket for sale).
