It's too late to buy LINK now but you can buy BAND on Binance because it's Chainlink's competitor and very cheap now, DYOR.
It's better to buy something that already offered a bright future rather than try to bet on the new coin that we don't know what will be happening with it for sure.
Link has already gained very big popularity and there was a lot of whales are also holding this coin right now. It was offering so many advantages.
