The price for iBeLink was $6k (so if you add PSU & shipping of bitmain) its 50% difference and 36% more efficiency.
I was considering
What about quality?--> bitmain's D3 have one FAN vs iBeLink have 5 FANS (which means more cooling?)
--> bitmain is using compact casing vs iBeLink using server type chasis (which means more airflow?)
What about price difference?--> bitmain price is $2700 and if you add PSU & shipping its going to be somewhere around $3100 to $3200 vs iBeLink price including shipping $6300 so it means 50% pricing difference
What about power consumption?--> bitmain 0.087 watt vs iBeLink 0.075 watt per megahash
What about delivery time?--> bitmain announced delivery starting from 15th September (means after 2 month) vs iBeLink promised delivery within 1 month
What about capacity?--> bitmain claims 15000 MHs vs iBeLink 10800 MHs (so a difference of nearly 36%+ hash rate)
What about reliability?--> In forums i read people claim that bitmain's equipment are not high in quality and unless you put them in datacenter or live in a very cold region they cause maintenance issues
CONCLUSION:On Power consumption & capacity:not a big difference, but winner is a winner, iBeLink Wins
On delivery time:One way that iBeLink can satisfy their customer on price difference is to start shipping out earlier so they will be happy.
On quality:Everyone have their own view but as per my research the miners who bought bitmain bitcon miners are not so much satisfied with quality, with iBeLink having 4 extra fans and more airflow by using larger chasis vs bitmains small chasis i think iBeLink is going to be a smooth ride.
On Price:i get my iBeLink on 15th August as my order was confirmed on 15th July , i will have 1 month and with that i am expected to make $4000 , so it will put me equivalent in terms of pricing as my higher price difference would be recovered. (so i have no regrets for placing iBeLink order)
My Vote:I support iBeLink because they were one producing equipment when bitmain was sleeping and we as crypto-people should not allow any giant to eat innovative players like iBeLink. Even look at bitcoin war going on , main culprit is this Bitmain who threatened with hardfork because they are largest supplier of bitcoin equipment & own largest pool
We should give companies like iBeLink chance and confident they will not shake our trust and ultimately prove to be winner.
My request to iBeLink is that they should deliver faster delivery to help their customers avoid price massacre initiated by bitmain.
Thanks.
