The coin is serious. You can see that the OP has been updated to reflect that. The coin has a lot going for it:
- ZS will focus on entertainment which is a hot topic atm
- Plans mentioned so far includes payment gateway system, commercial adoption (we saw and example last night) and wallet upgrades
- Coin is not a pump and dump coin as evidenced in the relatively stable price over the last few months
- Price is not fast rising that quickly burns out like the so called "fly-by-night" coins and has been slowly rising with good buy support
- Low circulation of 3.8m
- Coin has fast specs suitable for commercial adoption with just enough POS "interest" to want to rather stake in the wallet than sell
- Highly skilled and reputable dev (CryptoGir) with a good support team. CG does not over promise and under deliver. If he cannot deliver he wont promise. He is more of the "surprise guys, here you go" person that delivers something that would increases the price based on what was delivered.  He has also committed himself to the ZS project and will put all his effort into this coin that he can in-between real life priorities of work and family life.
- Great and mature community
- Mintpal listing is not a priority for the coin and is not the alpha and omega like same other coins. If it is listed, great, if not also great. As long as there is a facility where it can be traded it is enough e.g. Bittrex. Sure ZS will be listed on MP, but it is not a core strategy

CG has mentioned that he is working on the items above and there will be more not mentioned yet but that will be delivered as surprises. Consider ZS as a longer term investment, blue chip if you want, that will grow over time as features and plans are delivered and patience will be rewarded.

This is my personal view and how I have been observing things so far.
