Uff... yeah the ticket will be expensive this year, but at least that can be paid with crypto – I have much more of that than fiat, lol.

Next quest:
Finding cheap(er) accommodation

Check out Meininger hotel in Amsterdam Amstel, if you're fine with hostels. I will be there myself. It's only a kilometer away from the official hotels. I booked 4 nights in a 6 people dorm for 184€ – and that was the more expensive option including free cancelling.
