Either we come up with real innovative ideas to speed up transaction rate by 10 times, increase Bitcoin usage in real world, add more use cases for Bitcoin usages and Bitcoin becomes like Apple/Amazon or it goes down and down and become another Yahoo.
We need to innovate together to take BitCoin to 100-500k USD level.
No more innovations means BitCoin will die. Anything which does not evolve can not survive for long.
First, it's not true that "anything which does not evolve can not survive for long" - can get replaced by better solution, but if there's nothing that is objectively better, then there's no reason for a product to die. In our case, there's no immediate threat that some altcoin will replace Bitcoin, because none of them is more advanced than Bitcoin - they only claim to be so to drain money from investors.
Next, it's also not true that Bitcoin is stagnant - in fact it has more developer activity than any other coin, and there are many awesome solutions under development now that will boost scalability, privacy and expand Bitcoin's functionality. So, instead of creating alarmist posts, you should really spend more time doing research.
