One of the biggest factors that keep Bitcoin alive is the development team behind it. What if this developer team breaks down? Are there any other people who can continue the project in technical terms?
Well that could be challenging and people will definitely panic and will sell off their Bitcoins which will cause it to devalue but with the love people have for the Bitcoin project and what they stand to loose when Bitcoin development stall I think will motivate more developers outside the core to take over.
yes it will surely produce panic, because now people cannot afford to stop using bitcoin, and they will certainly motivate other developer to take the charge, but they cannot manage to stop gambling for ever. we can hope that in reality we will never face such kind of issues, which create panic to the people.
