With all the good news coming out in favor of bitcoin like
Expedia accepting bitcoin etc it's time to buy with the price going down. You will not be so lucky next week. I strongly believe it's going to reach $700 by end of next week!
it is the perfect time to buy a bitcoin because it's value is quite low but for the next few days it will pump again so you have a bigger chance to sell it for high value and earned a huge profits.
