It's certainly a more stable investment in an unstable environment but I don't agree that there is going to be just one coin at the top and everything else is going to zero; it doesn't work that way in any other industry.

That being said industries are typically led by a few that make up most of the market cap. Then the remaining slice is divided up into the rest; it could definitely be the same in crypto.

But if your good at researching and diversifying you can pick some of the little guys that are likely to go up 100-1000% while the big guys get their little gains every year. I guess if you're a passive investor that likes to leave your money in something and not think about it then the top 10 coins are where it's at. Hell for most people on this forum it wouldn't be a bad idea to put the majority of their roll into those anyways and throw tiny amounts into the other stuff.
