A post on Bitcoin Miner (@BitcoinMiner) looks into whether this is the end for the GPU used for mining. Excerpts:
“In less than six months, block 210,000 will be reached and with that event the block reward will drop by half, to the level of just 25 BTC.”
“Mining operators are preparing by either switching over to more efficient mining equipment or are liquidating operations outright — oftentimes due to the higher capital requirements needed to acquire the modern forms of mining hardware.”
“Even though the GPUs from this post’s photo are offered for sale as being used previously for mining (presumably for many months) they still have a relatively high market value compared to the price when they are purchased brand new.”
“There will be a rotation of hashing equipment. GPUs are being decommissioned where power is expensive and those same cards remain a valued commodity to those with access to power that is relatively cheap.”
