What are the reasons for the bulk of the bitcoin transfers? I read an article underlying the "dark side" of the internet and TOR network, and they seem to point out that bitcoins are now nearly the exclusive currency for the online "black market" (Note, they are not saying bitcoins are exclusively used for black market transactions)

Other - explain
I used bitcoin as my money to pay my bills in house. I also used it to provide my daily need in life. And lastly I used it to buy stuffs or things that I want to have in my life. But some of was just stock in my wallet so that if the price increase i can get profit. But i cant directly used my bitcoin because in my country it didnt accept as a rule if payment. I need first to convert it into fiat before I used it.
