Let's hope that ETH gets the attention it deserves by 2020. As long as the Casper PoS upgrade doesn't experience further delays from the dev team, the world's second-largest cryptocurrency by market cap will be able to gain massive traction across the crypto market. Otherwise, you can expect ETH's price to stale as people won't have a reason to invest in it. Scalability is a must for decentralized applications to become useful for the mainstream world. In this part, both TRON and EOS are in the lead. Ethereum must quickly switch from PoW to PoS if it wants to stay in the competition. I know that the dev team wants to implement the Casper PoS upgrade in the safest way possible for the ETH blockchain. But most people are tired of waiting for ETH to scale with each delay postponing the smart contract platform's most important hard fork to date.
One thing to keep in mind is that ETH's supply is infinite, whereas Bitcoin's supply is finite. This would greatly undermine ETH's price across the market in the long term. By this year, we could expect a short increase in price if ETH becomes a PoS cryptocurrency. Subsequent years could lead to short term gains, as people become excited about the platform. But the supply is what kills ETH as being a serious investment for the long term, unlike Bitcoin. After all, ETH is meant to be used as "Gas" for the execution and deployment of smart contracts on a global blockchain network.
Nonetheless, 2020 has been off to a great start where Bitcoin soared from $7.5k to just $8.7k in a matter of days. Ethereum has also experienced some gains in price, but not by a large margin. With something new and exciting for ETH this year, you could expect demand to increase like never before across the crypto market. There's high hopes that 2020 might become the biggest year for ETH. Just my thoughts
