I haven't tried that inverting thing but still i use bitcoin to buy me some nice things like t-shirt in the internet and some of computer games i played some and brought some of the items game then theirs gambling the game of my heart i really hate that game it makes me poor very very bad. but i hope bitcoin will take over the mall in my country so that i can easily buy things in the house or some cooking materials in my country only the "SEVEN ELEVEN STORE" but still i am afraid of buying foods in that store... maybe they will suspect me as some hacker or something.. Yes i earn money with bitcoin its really fun using bitcoin for income i really admire the creator of bitcoin i wish him Good luck!
