Hype doesn't matter for 1 coin which is Bitcoin which will be the number 1 crypto in 2021.Then Ethereum will folow bitcoin.But DeFi trend will affect the ethereum.If DeFi trend continues then ethereum will perform better in 2021 even from 2020.Then YFI coin which is DeFi coin.If DeFi hype finish in last quarter of 2020 then YFI will not be in good position.Recently Polkadot has created a great hype but I think it will be outperformed by Ltc and Trx.And recently some new coin has entered in top 20 coin in Coinmarketcap.But I don't think they can keep the position till 2021.So I will believe in Xrp,Stellar and Neo coin.Hope they will perfom better in 2021.
