Bitcoin had not attained much attention in the world of business and finance before the year 2009. It rose to prominence in the 2011-2012 period when it gained over 300%. Bitcoin has had a 400% growth in its value since the August of last year. As a result, venture capital firms and investors around the world continue to pay importance to the cryptocurrency.

In the first half of 2014, venture capital firms invested $57 million in Bitcoin in the first quarter, followed by another $73 million in the second quarter amounting to a total of $130 million, which is 50% greater than last year's total of $88 million. This is a complete contrast to the scenario in 2012 where Bitcoin firms amassed a relatively meagre sum of $2.2 million.

If you are living in the U.S. then Coinbase is the place you're looking for. Coinbase provides it's clients with BTC at an estimated mark up of 1% over the existing market price. Residents of the United States have the option to sync their Coinbase wallets with their bank accounts. As a result, future payment transfers are made hassle free. This company also gives you the option of automatic bitcoin buying from time to time. For instance, if you're interested to purchase $50 in bitcoins at the beginning of each month, Coinbase allows you to set up an auto buy for that amount.

Be mindful of the terms and conditions before you begin to use this service. If you have subscribed to an automatic bit coin service, then you will not be able to control the price at which the BTC is bought every month. Note that Coinbase is does not function as a Bitcoin exchange i.e. you buy and sell the coins directly from the firm. Since the firm has to source the coins from other buyers, you may face delays or disruptions when laying orders during fast market moves.
