Seller destroys keys on transfer. You seem like a smart person, so you will be aware that there is, of course, no way to irrefutably prove this. So, a couple of recommendations to my crypto friends looking to purchase any farm:
- Do not spend money you cannot afford to lose (and this is true of anything you do with Chia). When farming there are no guaranteed returns.
- Do not buy from a seller you do not trust.
To answer some additional questions that have been asked:
- You will need to sign up for your own cloud provider account (as above).
- The minimum commitment to the server provider post-transfer is one month.
