So much misinformation.....
- Development of EOS
This project has the same goal as Ethereum - the creation on its platform of decentralized applications (DApps). The creators of the EOS promise a more advanced blockchain than Ethereum.
Eos blockchain is highly buggy, they are facing lots of problems and it is not a threat for ethereum now. Eos price crashed after mainnet launch.
- Implementation of PoS Mining
With the introduction of a new type of mining, the speed of the network will also increase. However, the community is very worried about the level of implementation of innovations. After all, for its short history, the crypto currencies have already seen quite a few unsuccessful forks. Not all investors believe that such a transition can be completed safely. After all, in such a scale, the transitions were never implemented and all possible errors can occur. If such assumptions prove to be correct, then the course of the Etherium may collapse on the background of negative news.
You may be referring to ethereum casper
It's not running yet. It does not affect transaction time. It is also not a type of mining. There is no mining in pos .
Therefore, ethereum casper has not launched neither there was any new related to it, so it does not relate to the price.
When pos is running, it will probably have a positive effect on price, since coins will have one more financial use.
