Jacob Donnelly, director of marketing at CoinDesk, said: "Whilst we apologise for any delays, Consensus 2018 has received overwhelming interest and is the largest blockchain-focused event ever held in the United States. We are working to reduce the wait time."

It's not just Consensus which is bringing the crowds of course, with this week the first Blockchain Week New York. A full week of some 20 blockchain related events, some of which carry similar ticket prices, are scheduled around Consensus.

Meanwhile, the lambos were out in force to welcome attendees to the New York Hilton Midtown as the newly minted Bitcoin wealthy flashed the digital cash.
