Get a hardware wallet - feel safe as a baby.
Hardware wallet has nothing to do with what's been discussed on here, OP is all about the safety of Nicehash pool and people mining on the pool, you can only withdraw from a pool when you reach minimum withdrawal amount, Nicehash was once hacked and many got caught for years
i feel you, but as i understand its the link between NH and PM thats being compromised, therefore if you go straight for PM instead of NH and PM, you can withdraw straight from your choice of pool into your HW wallet, which cant be compromised.
