Hi, I'm a fan of TEK and I got quite a few of them in my wallet but I have a noob question.

What exactly is causing the difficulty to go up so much?  Today it's about 0.0018 but it fluctuates. All I understand is that I should keep my wallet locked and wait for lower diff before staking to maximize the stake rate.

Is the high diff caused by a lot of people mining it? (POW).  Or is it because a lot of wallets are open, or not open, or staking, or locked?  Ok, I'm sure you get that I'm totally clueless at understanding this. Would somebody be so kind to explain it to me?

Thanks!
