I am planning to buy 1 BTC. Do I need to wait few more days for a price fall?
I don't think you should need to wait for few days more, now we see bitcoin has least price of this year and in the next step bitcoin will be grow. Then if you are planning to buy complete 1 BTC, then i think it is best time for you. Just do it even i think you have few days left to buy bitcoin in a less price.
Yeah, I don't think that the price would be falling back, as the market right now had gained somewhat momentum and it will be maintaining that upward trend. So, here I believe that delay in the decision making will only cause you to regret in future as being optimistically I believe that you won't be getting it at this low again...
