Nah man, "too big to fail" means a central agency is willing to bail out a failing entity. No such central agency exists for Bitcoin. It's the free market at its finest!
We should all be prepared for failure. But realistically the only thing that keeps bitcoin going is the fact that a community of people believe it has value. This same theory, reality applies to all currencies and things of value. As soon as people agree that it doesn't have value it will fail and that will be it!
and it is true that failure must be faced with high self-esteem, who dares to take risks with a failure is probably a good way to start success as many others claim that bitcoin trading is never too late. everything is the way to how we achieve success by defeating fear
