Why are the bitcoins so expensive?
Does the price of them rising matter with the product bought with them?
prices changing every day depends on for example how many people buy and sell them through the night. Lots of people just sell them when the price is heigh, and buy them when the price is low.
and they try to make profit this way. but personally i think it is really worth to keep them. even invest in them, as i believe prices ll go up and up as the real cash more and more inflated. anybody agree?
