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...
In those times on where bitcoin was still on 6k range and you do have the money to invest on and you see the price climbed up to 9k then you will surely regret this matter or situation on where you do still doubt to purchase because you do fear that the price might go down even lower. For now I don't see we would able to comeback again on 6k but well theres always be a possibility but if you are mainly going for long term you can anytime buy on the price that you want yet you are just targeting for how many months or year.
