Alpha pretty good profit margin if they can upgrade 25 MH to 250.
If they deliver what they say when they say, which is still yet to be seen.
my peronal opinion is that they're scammers and will never deliver. They've not offered one single shread of evidence hat they have anything in development. The desire to purchase of these is quite string but my heart and brain tell me no.
I have units of order from Miningasicstechnologies.com and at least thay have a functional prototype and are willing to let people visit their offices...
I realy do hpe I am wrong about them.
