How much THETA do you need to stake?

I'm just curious, could you possibly enlighten me on a question I've been pondering? I've been hearing a lot about staking THETA recently and I'm trying to understand the dynamics of it. So, could you tell me, how much THETA do you actually need to stake? Is there a specific minimum amount required, or does it vary depending on certain factors? I'm really interested in getting involved in staking but I'm still trying to wrap my head around all the details. I'd really appreciate your insight on this matter.
