new ASIC for SiaCoin is coming:

Just after the announcement of their new DragonMint B29 Blake256 ASIC Miner for Decred (DCR), Halong Mining has also started taking orders for a new DragonMint B52 Blake2b ASIC Miner for Siacoin (SC) or other Blake2b POW coins. The hashrate of the new ASIC miner is cited as 3.83 THS for Siacoin mining at 1380 Watt of power usage, so a serious device in terms of hasrate compared to other alternative options from Bitmain A3 (already available) and Obelisk SC1 (upcoming).
Where the Halong Mining DragonMint B52 Blake2b ASIC Miner is suffering is the price, although almost half of the Decred miner they started selling, the B52 Blake2b ASIC miner is still pricey at $5549 USD. Even when considering that the price includes a power supply and free shipping it is pretty steep for an ASIC miner that can be used for just one cryptocurrency for the moment. Halong Mining should start shipping these new miners by the end of the month, so you can expect a pretty big jump in term of the total network hashrate for mining Siacoin.

So now we are expecting the second batch od A3s, the first od Halong, and the Obelisks (when? unknown)

I am expecting a big jump of value
