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?
In my own opinion, if the teams break down which means someone else who is not part of the team to take over will be very difficult because for another developer to take over another project in which he is never part of means tearing down the project and start all over again and thats why when the developer is no where to be found before the projects gets to maturity stage, then its going down and no two ways about it.
