RCon3 should not be listed as a free event

[kitblake]

On the page https://blockchainweek.berlin/events/rchain-devcon3/ under "More information" the Cost of RCon3 is listed as free. This is not the case:

• General Admission is $700.00
• Studentl Admission is $50.00

@kitblake: Right but the got a voucher take BLOCKCHAINWEEK and then it is 10 € instead of 700, even cheaper for students like that
