80% is a very good prediction accuracy especially in the crypto world where everything is so volatile and so hard to predict. So this gives quite a bit of weighting to their predictions and to the claims that they make. So it is very interesting to see. Me personally, I also don't personally know any crypto experts, however I make use of a lot of news articles as well as a means to just try and see what predictions are out there.Lolz thanks for your question,you know we have a lot of crypto expert all over the world and sometimes they are also an economics but personally I don't know of any of them but I have been reading news on popular crypto sites concerning prediction by expert and from my few years of following news on crypto sites, I can see that their prediction is always 80 percent accurate. I don't know if you have been following crypto news at all.
