If this is really true, it's really good to invest now and wait for the next bull run, it would be more worthy if we invest more compared before. The prediction is a really big amount of money and it would give more profit if things would happen according to the predictions.
Does that mean it's only good to invest when there's a random guy who throws a bullish predictions in the internet?
IMO, acquiring Bitcoin gradually since the price was down will eventually make you gain more profit than just buying when there's a lot of bullish news around the crypto space. Besides, this predictions, even TA's aren't guaranteed. The chances is still below 50%.
"If that is true?" Nobody is able to answer that question.
