For me, it will be Ethereum as it currently sitting at a market cap of over $132 Billion and a price of $1.2K as of January 2020. It enables the use of smart contracts that are executed after the right conditions are met and allows developers to create decentralized applications with no central point of failure. Ethereum 2.0 is a future upgrade that aims to bring beacon chains, Sharding, and Proof-of-Stake (PoS) to the Ethereum blockchain. Such changes will improve the speed and efficiency and also allow investors to stake their holdings and earn well.
Same here, I am also very bullish on Ethereum. Ethereum broke past an all-time high and made a new high. but this year It would cross $2,000 that most of the crypto twitter peoples talking about. Besides Etheruem I also bullish some top-rated altcoin like chainlink and Polkadot. I also bullish some GEM like tomochain, cotipay, Bolt etc. hope 2021 will be an excellent alt season. now waiting for the bitcoin movement. above all coins, Ethereum is my favorite and will hold for the long run surely. my target is $2,000
