You are not wasting any time, you have the conditions and if they are met it is up to you to do what you claim you can. If there is any chance that you will earn 90 BTC in 72 hours, I would personally spend a lot more time and effort for such a reward.

I don't want to go into the methods by which you claim that you can unblock an account in 72 hours, but if you have such abilities it might not be bad to give one vouch to the community by solving this case (of course if the OPs agree). That would very likely bring you new customers in the future.
