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.
Yet another bitcoiner who don't bother research and uses bitcoin price as measurement of bitcoin's success.
There are many innovations such as SegWit which already used and proved can reduce transaction fees and increase confirmation time. LN, MuSig & MAST are other upcoming technology which can help solve scaling solution, reduce transaction fees, improve user's privacy and reduce overall transaction/weight size.
Investors/holder shouldn't participate to make new innovation/development, i think what we can/must do are adopting the new technology, encourage others to use the new technology, donate the developers, spread words about bitcoin and encourage people to use bitcoin.
Also, only by Bitcoin acceptance by merchants/services/government that we can see more Bitcoin real life usage.
