Yeah, thats what Monero fanboys (or some of them) seem to not get. Monero will never be as big (let alone bigger, lol) than Bitcoin. Why? its simple, its super anonymous-only features give no chances at being transparent. This kills a large base of users and uses. Plus Bitcoin is king in all that matters: network strenght, adoption, network effect in general... which is all that matters, even more than who has got the best-ever technology.
Also, what people do not realize that if Bitcoin was completely anonymous it would have never been legalized. I'm pretty sure that even if Monero grows, it is going on the black list pretty quick (unfortunately).
I'm not saying that this will kill Monero, but it is definitely going to prevent it from taking a grasp at a larger user base.
However, Bitcoin seems to be in the middle of everything. It is partially anonymous, not too fast, not too slow; with a few upgrades here and there it could be considered
almost perfect (for our time).
Well bitcoin is not completely anonymous, you are right, i see many websites require lots of information if you want to buy some bitcoins
