This is regarding the tweet on closure of cloud mining:

"Dear Diamond Cloud Mining participants, Diamond Cloud Mining is having a soft shutdown. If you are well above 150% return that explains why your account is shut down. Those who are still behind will keep receiving rewards until that happens. No single user will be left behind."

Hi, may I ask how is this 150% return derived? Is it from the US dollar value of the initial capital or price of DMD at the point of funding with BTC x the number of DMD received? Or is it based on something else? Thank you
