I keep saying that so long as the blockchain technology is sound,bitcoin is secure. Money always follows technology and we have many great examples to chose from. Bitcoin will become increasingly more valuable as more people get to understand it.
Talking about bitcoin certainly relies on logic, because what counts is your money will be a lot (profit) or reduced (loss). So as a trader / investor, the general rule is to buy when the price is cheap and sell when the price is expensive. But the reality is not that simple because there are many parameters that affect the price of bitcoin, one of which is the media factor. Media is a source of information that contains positive issues or negative issues about bitcoin, and that will make the price of bitcoin rise or fall.
