ok, I accept your general point though - the market is still young. Today's top 20 possibly have more longevity than the ones in that list.

But as the market gets ever more crowded it becomes increasingly important to understand the exact nature of what you're buying into. Lots of coins have things in common but one thing that is a consistent pattern is that genuine originals do prevail. Look at the top 10 market cap - they're all originals in some respect or another and have held their positions for quite some time. (Despite even that fact, they've all gone through the x10 pump and back down to 20% all-time-high rights of passage phase).

I invested in Bitbay because it had hints of that uniqueness. But its originality is still quite opaque. Technologically it has some new features, a few of which it nicked from Nubits, others planned that are appear to be specific implementations of the smart contracts paradigm aimed at a particular market sector - online auctioning. As a pure technology though I don't really see what stands out but as a package delivered with ready made markets I do see how it could be compelling. Unfortunately it's the "ready made markets" bit which are the most opaque aspect of the package which is why I've been probing in that direction.
