Ok This is the situation. Baikal is stating delivery Baikal B 160 ghs  by January if they keep delivery promised you will be able to mine at high profit until June. In June there is Obelisk releasing dcr1 1500 ghs 28 nm semi custom asic and the sia miner SC1 800ghs. Then there is another company DCRasic which will be releasing the Materia 1 Turbo full custom asic 16 nm with hash rate of 3 ths (impressive) . So Baikal B with FPGA chips running at 160 ghs cannot compete with the new miners released in June and will only be profitable with LBRY and pascal. So this would be a high risk investment.
