Cloud based mining facilities in the past have done a good job at making your job more difficult for users to adopt a cloud based platform by not executing their part of the agreement...
That's true...
Trial plan is just a bonus for "people who are going to buy hashrate". That's why they can't withdraw mining reward from trial plan until they don't buy hashrate. It's not just an "airdrop" to attract people with email.
Sorry but what or how do you mean by "reach out to some of the power users on here"?
And yes, when a user signs up for a trail plan membership he/she can withdraw mining reward after purchasing any plan and reaching the withdrawal limit, and also it's possible to put it towards another membership.
Also in the end of this week we are adding a new payment method, people who have HSS(Hashshare) coin also will be able to buy hashrate with their HSS coins.
