recently i moved to a new place for work and i happen to get an opportunity for a free electric source and i was wondering if that would be great to start bitcoin/altcoins mining with asic hardware i never really had any and i have some questions
(note i can not get big and heavy asics because of moving alot i would like to small/light asics and no problem in having alot of them but not the heavy ones )
1- What is the best companies that sell asics with good user friendly experiance
2- What is the best hash/watt items that is out there now
3- is it hard to setup them ? i have alot of computer hardware experiance
4-how about shipping and its fees ( i live in africa )
I don't know how prohibitive shipping would be, but for the best Hash per Watt and smaller units, there ain't alot of choice. I'd go with used Antminer S3. There are very few manufacturer that still produce ASICs.
At the moment Bitmain. Spoodoolies make some ASIC too but with some bigger form factor and louder units, Avalon too, but the Avalon4.1 are kind of expensive and rare. If you have to pay significant shipping cost per unit, you'll probably have to go with the more recent unit, the Antminer S5, but the GH/$ is more expensive. The Antminer S5 is no longer on production so you will have trouble finding unused units. Even Bitmain now sell their used S5 only.
IT also depend on how much noise you can afford to have.
