I suggest we split the cost of CHF 150 (incl. tour and tickets for up to 20 participants) among the participants. I will pay it upfront and we can then settle in BTC or CHF. I hope we can learn something there and I also hope they can learn something about Bitcoin.
In my opinion Bitcoin is a very attractive concept to expose at a money museum. Live view of the blockchain, coins, mining gear, markets, statistics … I will also reserve some tables in “Linde Oberstrass” to have some discussions after the tour.
