There are a few cryptos that I follow that I think have a real use case and intrinsic value and chainlink is one of them.
Here are some reasons I like Chainlink:
1. it solves an actual problem, unlike meme coins like Doge.
2. It's been around for a while. A lot of the coins that were around back in the last bull run are now gone. Chainlink has survived. They must be doing something right while others crash and burn... they have been working on decentralized oracles for what is a long time in the crypto space and so have some expertise.
3. While I don't regularly check out their github and other communications, whenever I have, I've been impressed that they don't dodge tough questions.
For these reasons, I think they are more likely to be a sustainable coin for the long haul. There are other coins that I've researched that I like as much or more, but I don't pretend to see the future. It's important that every investor does his or her own research rather than depend on others.
As far as the exact number or percentage gain... I think that eventually it will go up quite a bit more than my "prediction". But timing is a b*tch.
I used to invest in stocks and it was the same thing. I'd have about 95% accuracy in my eventual price targets but my timing could be off by a lot. I think some people are better at timing these things?
