Some notable stuff to wait for in 2019 concerning bitcoin:
- Lightning Network adoption
- Privacy features
- Regulations(debatable if positive or not)
- More adoption in general
- More development in general
Will these be enough to push up the price? Maybe, maybe not; and just as always, no one knows when the prices will go up.
At the mean time, let's not always focus on price.
We may also expect platform like Bakkt and regulation like ETF. Actually, everything possible in this crypto world. It may take some times but it'll recover.
