Has anyone heard of them or used them? I don't see any reviews anywhere.
That tells us it is first indicator of being scam one. If there is no buzz then there is no marketing and thus rarely people are involved in this project.
Sometimes the names only tells us that this project might be all time scam. Who gives the name like that sun-mining? Thats crazy name and apart from that you know very well how these platforms work. I mean there are some big names in the industries which are not able to fulfil the customer requirement like hash flare, genesis mining etc and how can we rely on small new start up like this. I would say in one word that, dont invest into this shit. Its always ponzi no matter how convincing they might look in first place.
