They were kind of worthless for a long time

But now they are rising for some reason and I want to trade them
Yes, as i remember them those KIN tokens were dead but now they have restarted their project. Also the main reason to the KIN token to get the attention is that they are recently listed at the ftx.com exchange. This means that their is some potential behind this coin and also since its on ftx, it will gain a lot of attention because its price is very low (less than a satoshi).
