Chainlink is already to the moon, and due to bad market conditions and FUD from Defi, the Link price is affected,
only one way so you don't lose a lot, Sell and buy again when market conditions is good
You need to observed more closer, there are chances that the value may dropped more as the market condition right now is fluctuating.
You need to think wiser, if you plan to short make sure to have a good position.
But if you are looking for long term just let things happened and keep buying if you have spare money. chances to see good run once the entire market showed another bull.
I prefer to go for the long term and keep buying as you said because that will be profitable for me, especially if the price will go to a high price in the future. I think that will happen in the next bull run since when the bull run comes, every altcoin will have a chance to increase higher, making Link have the potential to increase. But before that can happen, we might see the fluctuating of the link price, and if the price is down, maybe that will be a good time to buy more.
