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.
I dont get the argument of why people mining with gpus are more likely to sell them than those mining with cpus.
GPU miners have more hash power hence higher chances of finding and solving blocks, thus more coins to toss around. They're also known to be the asic-adjacent miners of asic proof coins.
Hell, take a look at coins like GRID coin or UTC and see what GPU miners are doing to it.
