True, I am still doubting on purchasing some panda miners. However, ETC is not switching to POS soon and is almost equal in profitability. My only concern is that all hashing power now used for mining ETH will switch to ETC and will reduce profitability in mining ETC significantly. Is there a fixed date on which ETH will switch to POS?
I doubt that a lot of it will switch to ETC - ETC is fairly small.
A LOT will switch to ZEC.
Some will switch to XMR.
Smaller amounts will switch to smaller coins like ETC and ZEN and such.
Some will see the drop in profitability, say "no more" because they are in high-price electric areas and just sell out or turn their mining rigs into gaming rigs or some such.
The thing about GPU miners is that they can easily be adapted to a new coin that is GPU mineable. Bitcoin went CPU ➜ GPU ➜ FPGA ➜ ASIC. The same for Litecoin. I mined some LTC back in late 2011/early 2012 using older computers and heating a room in my house for a couple of months. That LTC has funded my current cryptocurrency adventures. My only wish is that I had held it until now, but hey, that's life. I have a low-end GPU miner (see my sig) that I use to play with GPU coins. I currently switch back and forth between ETH and ZEC, but can mine any coin that has miner software written to take advantage of my GPU.
GPU mineable coins require a relatively small amount of money and some software smarts to be able to optimize the hashing algorithms to run efficiently on a variety of GPU architectures (there are several different architectures for each of the two big player's GPUs). The end-users will have, or will build, their own mining rigs which can double as gaming machines. The costs to design, build, and sell an FPGA miner at scale (more than just code running on a widely available dev board) are significantly more than GPU rigs, and ASIC miners are significantly more expensive than FPGA rigs.
I like the idea of the PandaMiner machines (custom motherboard with off the shelf GPUs). It was just a matter of time before someone made the effort to do that. Think about it. There are a bunch of people who are building and selling (at a premium) five, six, or seven GPU mining rigs based on consumer motherboards. It was just a matter of time before a company took advantage of their resources to build a dedicated GPU miner.
