Only those that are already well established (Litecoin, Namecoin) or offer true innovation have a chance to survive.
I don't see any innovation in Bestcoin. If it's a premine than it is a deadborn for sure.

BitBar is already "rare", which is pointless anyways since the units are arbitrary. Premine/seigniorage means either "pump & dump" at worst or "thinks he's smarter than a market" at best.
