It seems every new cryptocurrency that someone creates these days ends up with people taking sides. It's either a "scam coin / pump and dump" or it's the greatest thing since sliced bread. Now, there are a few ways to make a coin very undesirable -- premining a large chunk of coins before releasing a cryptocurrency to the mining community would be one, and I'd also steer clear (long-term at least) of any coin that distributes a large percentage of the total coins in a short amount of time. Looking at Vertcoin, this is what makes it worth potentially more than even Litecoin -- and long-term it could even surpass Bitcoin (assuming it remains ASIC-proof).
1) It's more resistant to ASICs
2) It has KGW so it's resistant to pools and/or large fluctuations in the number of miners
3) There was no premine or other silliness on the launch
4) It pays out slow and steady over a very long period of time.
Why shouldn't Vertcoin succeed where so many others have failed (other than the name and logo)? At present we are not even at block 30K, which means there are fewer than 1,500,000 VTC in existence. Sure, the first week or two things went a bit too fast, but now we've leveled off and for the foreseeable future we'll generate blocks every 2.5 minutes. We are 810,000 blocks away from the reward halving, and KGW means we really won't hit the halving much earlier than expected. That means 33,750 hours -- or 1406.25 days, or 3.85 years -- from now, we will have mined half of all VTC. By mining slow and steady (as opposed to, say, DOGE, which will be mined out in about 525 days since launch), we avoid the potential for a massive pump and dump.
As to the lack of a premine, even BTC had one -- Satoshi mined it with a small group of friends for about a year before it really hit the public. Wouldn't it have been nice to be one of select few (some say around 20) people mining BTC that first year? 2.6 million BTC went out to a choice few; so much for the "currency of the people" -- and no significant giveaways ever happened, at least not to a point where anywhere near 2 million BTC was distributed among the masses. BTC was also a proof of concept, and the long difficulty adjustment times were at least in part a way for early miners to get even more coins... but probably two weeks just sounded "reasonable" at the time. We now know better. The new standard is KGW, and any new coin that doesn't implement KGW (or have some other way of dealing with potential coin hopping) isn't going to last.
Getting back to Vertcoin, the current network hash rate is around 2.7 GHash/sec, but since VTC is roughly twice as hard to mine (on a GPU) as normal scrypt, that's like a 5.4 GHash/sec coin. Compared to other coins, LTC is at around 100 GHash/sec and DOGE is at 78.5 GHash/sec; most other scrypt coins are in single digit GHash at best, which means VTC has already passed many of them. And that's hardly a surprise, as we've gone vertical in the last day.
We're now seeing VTC trade at 0.008 BTC, or already about one third the price of LTC. Some will call this a bubble, and perhaps it is, but I like to think this is VTC assuming it's rightful place as the number three cryptocurrency in the very near future. When the scrypt ASICs begin to arrive en masse, we'll see even more people start to look at VTC -- as well as any other non-scrypt coins. I'm sure we'll see VTC clones as well, but I'm not sure what they can offer that will be "better" than VTC. Faster transaction times? Maybe. More coins in less time? See points #3 and #4 above. They'll be a flash in the pan at best, but VTC is here to stay.
