Should we have to believe this?
There are times where we aren't expecting Bitcoin to reach X price but it is surprising us and it reaches that price in a short amount of time. I'm not saying that this price target will not be reached and even I'm very bullish on Bitcoin long term, reaching that price in just 2 years would be nearly impossible though I'm not removing the fact that it can. It can surprise us like what it is doing for a very long time already. Who knows? We might see it or we might not but I don't think that relying on just mere predictions is a good thing but just stick with the strategy that we built.
For me, I'm not believing in his prediction even though I'm bullish but I will not be surprised if it reaches that price in 2 years.
