Hi Charles, sorry i had not responded earlier... Please see the program in the mobile app: http://steemfest.com/app . The program is very diverse. There are writers, musicians, coders, developers, brokers, and yes also some blockchain and crypto people.
1 day = Plenary with talks, 1 day is touristy in Amsterdam's oldest part of town. There are still (some) tickets left! Buy with SBD via http://steemfest.com/#hotel
Again, sorry for the late reply. See you next week!
