Kudo to you for even knowing how to use bitcoin. I was never able to figure that thing out. hahaha! I use MG myself. Definitely normal to be nervous though. Lot of Scams out there. That is why my first cycle was a short cheap one. Now that everything went smooth the trust is there. What helped me was reading some of the reviews and frequently asked questions on their website. You can even message Huge Tom yourself. He seems pretty good at getting back to people and resolving their concerns. Your in good hands brotha.
