What’s causing btc to rally up

Hello all, been away for the past week or so and just checked the pricing.

What’s causing it to rally so high up rn? I believe there is the financial officer Powell stepping down and a new one coming in soon, is it related to that?

Genuinely curious, won’t be putting in more for the time being to understand if it’s over selling atm but just would like to know what’s causing such rapid growth in it.
