Well so far I think it's an excellent addition to the Crypto space.
It's got a very proactive team running it, and very transparent. There are a number of very interesting developments in the pipeline and rather than rushing them all out the door in one day - and messing it up, they are taking each step one at a time. This is not a get-rich-quick scheme, although a lot of people try to treat it as such, and it definitely is a scheme that is designed for the "average" player. No server farms, and anyone who tries to cheat or "game" the system eventually falls over. Suspended or barred.
The average miner with an old laptop running the desktop app will earn about 50 JSE a day, give or take. If a user has a web site that people visit, then opt-in embedded code will also earn them a little more on the side. Some people with really bad (kiddie) porn sites have fallen foul of the system and been thrown off. Others for various reasons.
In other words, the JSECoin system is not a system where the scammers and cheaters can get much traction. It's easy really, if the average user is making 50 JSE a day from mining, and maybe 50 JSE a day from a well attended web site, the user who is making 1000 JSE a day becomes very visible to the admins. So it's system that is designed to exclude those who want to Farm the Coin.
With its slow growth, and the focus on Merchant interface using JSE for transactions that are based on fiat values and translated to JSE, and the forthcoming Ad network makes it very attractive. So far it's listed on LATOKEN and IDEX, a couple of smaller exchanges, but just right to give the coin some traction now that the ICO has ended.

I got on this coin early, and am happy to wait for it to develop over the years. If I wanted quick-money I'd go to the horse races...
