You can build almost anything cheaper than you can buy it. A Bitcoin miner is the one exception. The reason is strange: the chip that does the work is never sold to you. Bitmain and MicroBT design it in-house and keep it. The only way to get one is to gut a finished miner. Matching one factory miner with DIY boards runs about 10x more. https://t.co/7nnCpgbwvL #Bitcoin #BitcoinMining
