I bought some coins, for now i like how it works but i have many questions.. Will try to scrap from forum

Hello, can anyone tell me how this stuff work, i need someone to explain me how to trade safe on Rektex and how it works, I don't want to loose money bcs i missed something.
How to stay safe and all other necessary hints that can come handy, can i sell an ICO in development stage which didn't hit an exchange?
Is there some guide for trading?

Thanks
