Maybe. They have 6 months to make some money off of it before the halving. Halving is coming.
The usable life of a miner is just 6 months. If you cannot ROI within 6 months, you will never. So They should have planned for that.
What you talkin' about Willis? I got S3s that have been going nonstop for over 16 months and will continue well past the halving.
And I'm sure lots of college kiddos "leeching" free power for 4 years at a time. For me mining ROI is a secondary consideration - my main concern is keeping the network distributed.
I know your first consideration is the free power. Without free power, there is no way you will ROI and continue mining with S3.
