Spectrecoin really is a quality project, grown from a dedicated dev core now coming along with a grass roots awareness push. What struck me was how frickin nice and polite they were on slack and how quickly they were to reply to questions.  I sincerely believe that this is a project destined to succeed, because unlike some communities for other privacy coins the people involved are just a fantastic group of individuals.

Loopring, Req, Neo, Populous and Spectrecoin

Loopring, and probably Chainlink as well. Tons of market cap ceiling to go on each

Looking into Spectrecoin (XSPEC), it seems intriguing.

The tech is similar in many ways to Monero but what separates Spectre is that it's proof of stake so you get a 5% yearly interest. It will also primarily function through the TOR network with obsf4 to allow usage in TOR blocked countries like China.

Right now the market cap is hovering at 6-7 million. The development team is working ultra hard to roll out the next updates. Mobile wallet staking will come in 2018. Monero is at a 3.5 billion market cap. It is great tech. But it seems likely that privacy coins are all going to grow in need as governments are going to try and contain capital flow through the more public cryptos like bitcoin.

It's no Monero, but there's no reason why Spectrecoin coin can't co-exist. Someone put it like this, while Monero is a privacy Bitcoin, so a secure storage of value, Spectrecoin aims to be like Litecoin. It will try to be method of lightweight, fast private transactions. I don't see how it can't hit a market cap of say 100 million like a Verge or 250 million like a PIVX. Just look at this chart and compare the tech. If Spectre does manage to blow up that's some absurd returns.
