Haejin uses EW to predict future prices. It doesn't predict timescales, so his predictions could be a long time in coming to fruition. A lot of people don't realise this and follow blindly hoping to make a quick buck and that when he makes a prediction it will happen in a matter of days. He is the best out there for EW however you have to realise the above when reading his predictions.
I'm still still undecided about the mantra "a news or event will arrive to justify the forecast". Crypto could well be a different beast and the tail possibly wags the dog meaning BTC dictates what happens to all ALTs. In addition despite being decentralised technology, the market is clearly manipulated, Reducing the effectiveness of EW, resulting in predictions that look wildly optimistic or even incorrect. In using past waves to predict the future trend, it can also look like a person using EW is constantly changing their mind, as they react to what has happened, and update their prediction. Again this looks more like a prediction based on an event that has just happened rather than news or event arriving to to justify the forecast.

Sorry for long reply but in short people should stop bashing Haejin and instead understand the above principles and appreciate the insight he gives, rather than following blindly. Yes he is earning huge sums of money in STEEM, but we happily let footballers get paid $300,000 a week so let's put it into perspective.
