I decided to flip my D9 on eBay. After reading, "The State of Cryptocurrency Mining" by David Vorick, and seeing my other miners have yet to ROI, and probably won't, I'm finding this game to be ridiculous.
Interesting read. As I mentioned earlier in this thread, one must assume manufacturers are also running these miners behind the scenes. David's blog kinda of confirms my suspension but make no mistake, Obelisk will be doing the same thing. Why the heck would any manufacturer sell their "money printing" machines if they can keep the profits all to themselves? It's another avenue to generate revenue to build more machines, for their self.
One of the things that caught my attention is David mentions at the time of his writing (5/13) is that Obelisk will be shipping their first miners in about 8 weeks, putting their launch closer to July instead of June as many expected if that's true. The biggest concern for all miners is the market being FLOODED resulting in longer ROI, if ever achieved. We should all be aware that mining calculators are current state and not a good gauge of profitability months or even weeks down the road. Many of us have learned the hard way, myself included.
The D9 is no exception. I've seen the profitability drop from $200/day when I ordered/waiting on batch 1 from Innosilicon to current state of $89/day, granted the market is down everywhere today but it's not the first time I noticed the $80 range. That's assuming all batch 2 orders are online now. Innosilicon is currently onto their 3rd batch so I would presume profitability will take another major hit down to around the $50/day or more when those machines are up and running. Lord help us all when the Obelisk miners get online. I think we'll see it drop to around $20 range around that time.
The only positive is the longer it takes for competition from Obelisk, hell even Innosilicon, to get online the quicker the chances are to ROI. I'm happy that I purchased the D9 batch 1 when I did but have to admit, I'm much more reluctant to purchase this current batch (which I intended to do) and any other batches in the future seeing how quickly Innosilicon releases additional batches diminishing profitability very quickly. It's very much a cat and mouse game and we're at the mercy of the manufacturer.
This major concern would be somewhat alleviated if releases were pushed a bit further apart allowing us to get closer to ROI before the next batch becomes available. I think, let's all hope Innosilicon truly is a different company than Bitmain with respect to caring about their customer base by NOT flooding the market. I've had a great overall buying experience and looking forward to repeating business but at this rate, there's too much risk.
**Inno, please hear this plea. PLEASE slow down on your releases so YOUR customers are not burned by purchasing your miners. Let us get a bit closer to ROI before releasing subsequent batches.**
