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.

It's up to you to believe it or not, but I've never heard of that guy, except that I can guess from his last name where he comes from. He’s just looking for his 5 minutes of fame, a little free PR and that’s it. People who need the opinions of some strangers to invest in something usually lose their money sooner or later.
It’s funny to me that everyone is waiting for some perfect moment to invest, and there were so many opportunities during 2018 when the price was only $3000, or recently when we had more than a 50% drop. I know most just want a quick profit, but then be careful not to let the 2017 scenario happen to you - many were convinced they should buy, when the smart ones were actually selling.
