Oh, nice info, thank you guys. I hate scammers as they fool regular traders/investors and that’s awful. Frauds are everywhere, so we have to be careful when choosing exchanges, ICOs, or cloud mining services, etc. The only thing I can suggest is reading review of exchanges here https://www.theproblem.wtf/ or other trusted sites to understand which platforms are legit and which are not.  Also, it’s crucial to spot red flags like unreal people in the team, fake links to partners, large but uninformative documents and so on. Be safe and don’t trust frauds, please!
