All true statements, but just like bitcoin, it will become useless at some point to mine ETH with GPUs because the difficulty will increase with coin growth. When that happens, choose another coin and put your GPUs to work. But there definitely is a shortage, went to get some radeons and had to order online because stores were sold out, like literally nothing but the shitty ones left lol.Just ordered my 6 GPU's. One in hand and 5 coming from Cali next week. Check this article out though.. what do you make of it..?
