I have used this cheat on two separate accounts including my main. 

-Is it safe? 

Yes. Both my main account and my alt account are stills safe.

-How can I trust? 

Look at the community, read the reviews. It's not bullshit. This is by far the best community for cheating and just for gaming talk. Everyone I have met here is helpful. 

From the instant respawn (god mode) to the OPK this cheat is more than just an easy crucible win. 10/10 recommend.
