I was already all set and ready to pay $10k for an A5 pre-order, and my wife stopped me...I am glad that she did so...
now i am not sure 10k for one A5 could get ROI for how many months? or ever ROI?
Your wife is a wise woman... All this hash will be pointed at mostly Dash. I don't know how long it will take for a Bitmain D3 at $1500 to ROI let alone a 10k miner unless it was shipping today you won't likely ROI any time soon.
i order 1 a5 oct mid batch... after reading all this... personally i suggest people who already pre order we cant do anything except tat inno will delivery on time and hopefully they r trying the best to make their stated performance true... so ones we get a5 we mine and safe keep dash for at least 4months and i think dash network hash increase and price of dash will increase too... base on coinwar today i guess difficulty 1m with 30-35th/s network hashrate... oct end lets just start and assume with difficulty 10m with 300th/s network hash, you will still at least get 15-20 dash after 4 months of mining (end feb 2018 )i guess... and u look into aug to sept dash price increase when currently just ibelink 11g alr ship out to miner +(baikai miners) out in the market for x11 mining... i kind off think roi is still in 4 months for sure... i believe dash will pass 600usd by early next year at least... so....... get your machine mine and keep and wait for dash price to increase then sell it off at 600/per dash at least and then u can count your roi from there... of course for other not yet order i still think go for d3 instead of inno a5... somehow i still feel not too late to order d3 if shipping is in this year or jan 2018... but inno a5 9999usd does not decrease price by the 3rd batch it definitely a no-no purchase for that... u could actually do research about scrypt asic L3+/A4 miner realease batches time on to market and compare the increase of litecoin network hashrate against litecoin price increase as a example... it just mine and keep and sell at the right time i guess... still not a long roi... till now scrypt asic people r so over crazy about it too... mainly because more alt scrypt coin to mine... and who knows could there be more x11 alt coins in future to mine more profit than dash? ummm.. just a pcs of personal suggest and thinking to share... sorry for bad english...
let us know, they are now accepting Batch 2 (delivery Dec)
