I AM very confident with the $1900 one :
1. More than 3 months after monero change algo (just a little different than cryptonight), X3 might update its firmware just like Baikal's miner.
2. For Monero only, with total 4 batch of X3s and if each has 10000 units for total 40000 units means hashrate will rose by 8.8 ghs. With current around 1 ghs and X3s 8.8 ghs for total around 10 ghs, it still mining $20 a day or $600 a month (220khs of cryptonight in Nicehash $200 per day now). Usually Bitmain's Batch only 5-6k or, it will more profitable.
3. Even if it can not mine Monero, there are many coin that can be mine AND there are auto switch pool or rent service like Nicehash so its still profitable.
4. Competitor doesnt have anything big to compete, so network hashrate wont be that big. I would love to add Halong but their miner not be seen anywhere.
5. I always touch break even point at whatever Bitmain throw, even D3 that hated by everybody. All calculated by coin not USD
The point of mining is INVESTMENT for a long time. If you mine with S9 right now and sells the coin right away at 8-9k, then you miss the point and of course you will have big loss. Hold the coins and set sell order at your favorite exchanges with 5 times of its price right now OR atleast wait for next halving.
Im not siding with Bitmain BUT they almost counter every competitors with better hardware. I bet when new SHA256 miner with 2-3x efficiency of S9, Bitmain will release 4-5 times better OR cheaper.
The problem with the above logic is 1) bitmain has already mined these and is dumping 2) bitmain will put out asic's in massive numbers ...right now they have a D3 X11 miner
at 550 usd...but if you gave me a FREE D3 x11 miner NOW at 12c kwh (summer rates starting) I'd lose $$$ ...that miner as an example will never ROI and has been out for what
less than 5 months?
Being bitmain they are very likely to do the same with the x3 stuff....they have mainly done D3 (x11) and S3 (siacoin) and this new x3 miner in my view...to keep their
factory folk employed in the downtime development of a new scrypt-pow and or sha-256 miners they will mine like hell for 4-5 months and then release to us in the fall 2018
got to keep the factory plant open doing something and the designers and etc....but the real money is in what they are developing in the background for their own use
to dump on us 4 months in the future say ..when they start to puke out as well
rinse/wash/repeat ...their 4 billion dollars in profit last year had to come from somewhere
(bitmain: real evil is the only way to go....go big or go home!) (tm: bimain)
Well seeing x1 and x2 from halong and shipped early, almost all X3 fvcked up mate (if they really shipped).

For D3 roi Im not in 12c and actually I have my own power source. But again please keep in my quote above, if Im in your place I still mining with D3 and pay power from my salary then keep the BTC since I know BTC got almost 20k last year and more than 21k in some local exchanger. I never calculate break even with usd since I trust in BTC, it will grow and rise higher especially at halving.
Right now a 19.3 ghs D3 can make 0.00051125 a day and its looks very stable so it can make 0.138++ until Dec 2018. Hoping it double last year high so 40k * 0.1380375 = $5500+. If I dont have Faith in BTC, then Im not here anymore mate. Anyway my last batch D3s have Break even last month 😁
