Bitcoin is green again, do you thing is good time buy now .
Bitcoin has been green from the beginning, what is currently happening is increase acceptance by the day, which is one of the reasons to buy bitcoin now. Again ,because no more than 21 million bitcoins will be made (the last bitcoin in the year 2140). At the moment almost 13 million bitcoins are in circulation. You may wonder why it will take until 2140 for the last bitcoin to become available but that has to do with the increasing difficulty of mining bitcoins.
Because the total amount of bitcoins in circulation can never be more than 21 million, the price is very likely to go up as time goes on.
