You're welcome. A promise is a promise!

It may become useless, if proof of stake does turn out to be the future of crypto. It is far "greener", but a transition for all coins certainly won't happen within the period of your mining contract, so I think you're safe there.

Ha, I feel that coins are going to stay here, Proof Of Stake is a terrible idea, I would rather just mine stuff, gives me a use for spare hardware and makes money. Proof Of Stake basically screws that. I would stop using crypto if i couldnt mine it
