Of course its users will surely affect it but the main reasons behind this is I think the news behind Bitcoin and any other cryptocurrencies as they are the main basis of people on where, when, why they are investing in. And I think the other is the traders that is playing the price of bitcoin as it is so volatile when there is a big moving in the price of bitcoin.

If you take a look on the recent years of bitcoin's price you can see that it is always going high every year so I think it is wise to invest now and just trust the system if you are hesitating to do so.
