I'm order #20147, considered cancelling, but didn't.
They have a policy of allowing customers to upgrade existing orders and not lose position in the queue. Considering an upgrade, bion lol!
But yes, it is a scam because the more they sell, the less they're worth. Hence ponzi or shovel scam. And this is whole problem with mining cryptos IMO. And I got an idea to fix it...for another thread.
