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!
If bitcoin will be going to be a big fail it would start falling now. In terms of its price, value, volume and stock in the market we could make sure that bitcoin have a better future for investments , transaction and for business purposes. Numbers tells it all. Number cannot lie and when we look at the current value of bitcoin and we will look forward for it to used it in different types of transactions, we could have the best opportunity for us to earn and to have profit in the future.
