This is quite an ambiguous situation for investors. Should we sell now before GPU miners start to dump their coins and the price will go down? Or should we wait for the announcement of new feature test results when the price will probably increase? Which will come first? Haven't decided yet.
Personally, when I see the hash rate go up, it usually means that it gets harder to mine for everyone. If only a few people had the GPU miner (which I personally think was the case), then they have an advantage. This is when it gets easy for some to pump and dump. When the playing field is evened out, there isn't as much advantage to pump and dump.
I have low end equipment, I'm just keeping up with what I was making before by adding GPU
I have noticed the highest miners have not suddenly increased their capacity, therefore, I suspect they already had Gpu miners working.
This leveled the playing field.
I can't say some fool will dump their coin, but I can say, if they do, and I can, I'm a buying 'em up!
