All ETH holders are waiting for the moment of Ethereum 2.0 launch, which until now has not yet been released. But don't worry, I'm sure they will release it in the middle of this year, or maybe it coincides with the 5th anniversary of Ethereum, on the 30th of July later.
Yes. We've been waiting a very long time for the dev team to adopt PoS on the ETH blockchain. But day after day, they keep delaying the same. It's somewhat disappointing for the ETH hodler, as its competitors are already one step ahead of the game. EOS, TRON, and Cardano are much more scalable than Ethereum with faster transactions, and in some cases, no fees (especially DPoS chains like TRON and EOS).
Perhaps you're right and the team decides to implement PoS on Ethereum by July this year. It will coincide with its 5th anniversary becoming an exciting event in crypto land. But rest assured that if this year there's no improvement for ETH, people's interest into the cryptocurrency will continue to decline. And if this keeps going, you could expect ETH's market share to decline paving the way for its competitors to take over its second place in market cap. I hope that I'm wrong and this would turn out to be the biggest year for ETH yet.
In the meantime, prices are still below $1k per ETH. You could easily accumulate Ethereum until the time comes to sell it. With a PoS version of the Ethereum blockchain, people will buy more ETH than they will ever sell. After all, the Blockchain will reward hodlers most. The more ETH a person has, the more the reward will be. While I'm not quite fond with the unlimited supply of ETH (which leads to inflation), it has still managed to retain its value within the mainstream world. The dev team could easily decide to implement a hard cap on ETH's supply if the need arises.
Nonetheless, there's no denying that Bitcoin's halving will have a positive effect over Ethereum's price across the market. This, combined with the PoS upgrade, should make 2020 the biggest year of Ethereum yet. Just my opinion
