Hello, I still do not understand the mechanism by which bitcoin or ethereum, or any other virtual currency, increases or decreases the price / value.I kept ethereum for 2 years and not much happened. only bitcoin had a big change of value during years

Not only the price of bitcoin has change in these 2 years. Hence almost all the crypto currency has changed a lot in these days. If you bought 1 ethereum before 2 years how much it was? It was not more than 170$. And now it is about 2000$. So it is about 10 times in these 2 years. For more clarification please have a look on the screenshoot.
