Hey all, im in dire need of bitcoin and im trying to figure this out, cause its really confusing to me. But just to double check before i do something stupid, I can buy a moneypak from a place like walgreens or cvs, and then trade it with someone on here. Say I have a 50 dollar moneypak. Going by the "last MT" price, i can trade with someone on here and receive around 3.99 bitcoins. How does that transaction take place? Either way, lets say it takes place even though i dont know particularly how. They would then send the bitcoin to a wallet that I have on blockchain, and then I give them the moneypak. Then I can put the bitcoin wherever i want to, anonymously, and then they have my 50 dollar money pak.

CORRECT?! Please correct or inform me in any way. Ive read many articles but there are so many different services and methods and what not I don't get far...
