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!
Surely this would be the best time to buy, since price is at dip make it as an opportunity to gain greater volume of coin. In few weeks, the price will once again recover and regain which will no longer allow you to gain more. Dont wait for the price to get more lower, people are now having great demand on it since its affordable already. Surely the price hit back and continue to grow in few weeks. Buy and Hold, bitcoin has a bright future.
