Hi I've been a long time miner with GPU but I'd like to let the people know that you shouldn't be investing with GPU and wait for 8 months (MIN.) to 1 Year ROI.
ANTMINER (ASIC) is = with 7 GPU if you are going to buy but the ROI is way faster for ANTMINER D3, with just a month or 2 weeks ROI. you can search about it and start building your own. It's sad to know that few people know about ASIC.
SEARCH and WATCH about it.
For people in the Philippines I can help you with the unit availability because most stocks selling online and out of the country are out of stock already. PM me if you want a FAIR MINING.
