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.
I'm fond with your enthusiasm, and yes It's great to think of more innovative ways to upgrade bitcoin. I would recommend you read more about the soon to be released "Lightning Network" It aims to decrease the fees and introduce cross-blockchain technology which would take bitcoin and Crypto to the new level.
