All of his statements since 2013 were actually true.
That's quite a statement to make without provindg a link to the predictions. Google shows lots of recent news about it, but I'd like to see the predictions made in 2013, not "predictions" that were posted afterwards.
Besides, considering the large number of predictions made by many people, some of them are very likely to be correct. That doesn't mean they'll be correct later on too.
None of his predictions fullfill the requirements for a prediction which are quite detailed. In order for a prediction to really be a prediction you need to specify an exact date and an exact price for instance. Something like bitcoin will reach 15k in 2019 is not a valid prediction since its too broad.
