Well /biz/ was telling everyone to buy chainlink at 20 cents, it's now 26$, and they were posting all sorts of information to back their claims.
If information giving more than x100 ROI in 3 years isn't quality enough for you then I don't know what is.
One would be wise to look past the anonymity, racist jokes, homophobic jokes, etc... to find what you want, it's like diving in a lake of shit that has treasure chests under it you'll find it if you look hard and deep enough, but you'll have to swim in shit.
