Bitcoins are not continuous rising but there are allot of people who thinks it is only rising but there are also allot of drops most of the time the drops are not really big but it are
drops and that is never good for the bitcoin. But after drops also comes price increasings and that will happen more than the bitcoin drops.
What people are trying to say about continuously rising is the time that will pass like years. Of course it is not a consecutive rise but even though we have a lot of drops there were still a rise that will make the prise of the coin into higher stage.
