Now & After 6 years from the creation of Bitcoin by Satoshi Nakamoto , what's the worst case scenario that could happen to Bitcoin and make it dissapear once for all in your opinion , personally I guess it will be little bit hard to get 3 billion USD market-cap business destroyed just like that .
Bitcoin will never disappear, but the most troubling event at this stage is how "the person Satoshi left in charge of the code has now left the core team."
This has made a dire situation in terms of development, leadership, and direction. With that being said, however, Gavin does have some pretty dumb ideas from time to time. His hairbrained scheme (BIP101) to double the block size every two years is probably the
worst idea since the invention of software.
The best thing that could happen would be for me to take charge of the development. It doesn't take a rocket scientist to figure out you simply raise the block size limit to 8 MB now, monitor network growth, then implement future forks/updates as needed. This is one line of code change basically.
