Go tell that to people who call crazy Bitcoin prices.
Just google "bitcoin target" and you'll even many 6-digit expectations, mostly around 100k and even 400k (!!)
For a smaller-cap coin like XRP (though it's still big overall, but smaller than BTC) a 10x target isn't that crazy, it went 20x last time in just 1 month.
PS: With this post I don't mean that I prefer XRP over BTC nor that I prefer BTC over XRP, I'm just stating numbers.
I have to agree with the context of this post.
As far numbers crunching is concerned the volumes are there for everybody to see.
