Im buying bitcoins when the price goes down and hold it for a couple of months before selling it, cause when bitcoin goes down it will take weeks or months for it to go back and go up..
This is also what I'm doing for trading, buying of bitcoins when the price is low and going to sell it when the price fluctuates to a higher price,
since I'm expecting for the price increase of bitcoin. I will just hold it today, and going to buy again when I got a profit to it.
now prices have gone up quite high, it certainly would be a decrease before approaching halving. so I will buy when it goes down, even though I had already bought when the price of $440-450.
