I really don't want to buy altcoins now. I prefer to hold my BTC and ETH or even buy more. I'm not sure which altcoin will pump this year. But I am sure about BTC and ETH.
With upcoming news coming from this two coins those who have good understanding and knowledge about this crypto project will keep buying while price still on it's cheap position, upcoming forks which has been delayed for ETH and BAKKT for bitcoin will make some positive momentum, though there's still chances of negative impact but mostly it can bring something to those coins.
