This coin has touched its all time high for the second time after its price touch the all time low $0.12. Moreover when I see on coinmarketcap the return of investment has gave 2.724% for its investor. I think the chainlink is deserve to be choose for your portfolio and hold it for long term investment. And regarding for basic attention token (BAT) seeing the movement price in a few days ago indeed this coin price is very tempting.  A few days ago this token price has increased for almost 13% and after that I can't the crashes that happened as usually happen on the coin when its price increase. You can choose both coins for your investment place.
