First of all I hope that you bought some before it reached the current levels otherwise you missed an incredible opportunity, now about the topic, the most simple answer is that the demand for bitcoin has raised dramatically and with it its price as its supply is very limited.

But why the demand has increased so much? Because people are realizing that fiat currencies and the economy in general is the biggest scams this world has ever seen and that the pandemic has accelerated its inevitable crash, a significant money of all the fiat in existence was printed just last year and this is not sustainable and people are going to do whatever is necessary to protect themselves and that includes buying bitcoin.
