Have 1 million of links, 100 k of arks and 2k of neo, plus 10 k of pivx.
Since I am old fag, my investment strategy is to invest based on meme strength index. All my investments are from /biz/ because if a coin will succeed, first it will be shilled on /biz/. Trump coin, Signatum, chain coin, ants, ark, pivx and so on were shilled here first on.
For example I bought ark at 0.18 cents, link at 0.18 cents at ether delta and so on. Of course it doesn't mean it will moon because it is shilled in here, but if shilled coin has good fundamentals, it will moon. I mean go to Wikipedia and read about smart contracts. In critique part of article it mentions a lack of oracle's. The problem perceived since inception of blockchain.
The only way chain link can fail if someone is better than them. It's like investing into internet retail shops in 90's. If you bought amazon's stocks, you have won a lottery. You knew that internet shops will be a future, but didn't knew which one.
