It's so hard to choose what ICO you are joining for. I suggest you review first the ICO you are joining. Check out their website, social media pages and also what is their platform. Here is one ICO that I have a good review. Check https://www.swachhcoin.com. They do have a very nice platform for waste management. They will give monetary incentives to their users to manage their waste properly. whereas, traditionally people used to pay for their waste to be collected at home. Their token sale is also live now and it's almost 41% remaining before they reach their hardcap. The success of this project is very near. So I suggest you also take a review on this project.
