I prefer to exchange bitcoin on the market .. because with the exchange of bitcoin I will benefit from the exchange of bitcoin. buy at a low price and sell at a high price. that's what I often do to get bitcoin. I do not like gambling, because it will make me lose all the money. indeed if I win it will probably benefit. but it is very difficult. often I lose in following aitua gambling. I want the bitcoin service acceptable to all the existing companies. payment using bitcoin is easier than other payments. because payments use bitcoin peer to peer, do not use third party.
