Well, there is no set time to when to buy and sell bitcoins. It all comes down to your gut feelings. Usually, follow a market trend and that should help you out. Or events such as the segwit on August 1. Bitcoin's price is currently in the decline as many people are scared because of it, so this is a good time to buy. It is impossible to when you should sell or buy, but you can make sense of it by following news and trends.


Only If it was this simple.....

However, Bitcoin is still in its evolution phase, meaning that prices will increase a lot in the future as its popularity grows. I would say that in the next year or 2, it doesnt really matter when you buy bitcoin as you will still be making a lot of money in profit.
