Quantstamp was listed on first exchanges - Binance and Huobi.
The price is still quite low, so it might be a good entry point.
I like quantstamp but I think I am already late. I need to wait until a market correction to be able to entry. I have heard many good things about it although I do not know yet it the idea behind it has that much possibility for growth... seem a bit limited.
Limited? It is trying to solve the main issue in the now 2nd generations tokens - scams and bugs. I would be much more inclined to enter into ICO for token with QSP verification that just random token. Once QSP will have the working product only moon can stop it.
