It finally seems that on Bitmain's website, a few machines have become available again with a March 2018 shipping deadline, even to Hungary with a shipping cost between $90-150. The Bitmain AntMiner A3 is a mining machine using the Blake(2b) algorithm with which we can mine Siacoin at a speed of 815 GigaHash/second.
To operate the machine, we need at least a 1600-Watt power supply, or the best and simplest option is to order a Bitmain APW3++ power supply that provides sufficient energy for our A3 mining machine and comes with appropriate cabling.
