Don't worry about bitcoin price at any time because if you invest at low price then you can sell at high price in future. Big pop up always happen so don't get panic when price falls. This is common in the crypto world just hold the coins soon big pop comes. When the price is low, make use of the opportunity to gather as many coins as you can and sell them all when the pop up situations arise. I would advice you to hold back until you find a good hike in price. Try to get a good turn over.
The reason why a lot of people make mistakes when it comes to the market is because they focus their attention so much on the current market movement and with the mindset of how the market is going to be in the short term, they tend to miss the idea fully and then before you know it, they start making horrible decisions that will affect their long term hope. Whether there is going to be a big pop up or a pop down, all that matters is the future and if you cannot trade, then it is better to just go find something else doing to occupy your mind.
