As a long term investor my only suggestion for you is that don’t wait to buy the Bitcoins, if you have funds, then just buy the coins irrespective of the price. Bitcoins are very valuable coins. They are limited in numbers. Hence if the demand to accumulate the coin increases (which is actually happening), then in order to meet the demand the price will go up. Hence, in a long go, there is more chances that it will give you solid profit. Hence, accumulate as many coins as you can and hold it. Definitely you will make good profits.
