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!
Now is still a good time to buy bitcoin because the market is red, but I'm sure bitcoin will go up at the end of the year as many bitcoin users say like that. I can only believe in bitcoin for the future.
