@Charles-Tim, Baba Which site person fit get the mining machines and how much on estimate using the current Dollar-Naira rate e fit cost person?
I have tested out some sites online to check for mining products, especially ASICs, specifically Bitmain Antminers. I found AliExpress looking more promising, the company is also owned by Alibaba Group which is based in China, I see the company to be one of the best sellers of such miners. You can check the site out, but ASIC are expensive, although the old ones like S9 are not that expensive, but consume more electricity than usual, it can be alternative forgo but I only see the new miners on the site.
You will need to check out the miners yourself on the site in which the hashrate generate are included
https://mbest.aliexpress.com/m/promote.htmI have also heard that Antminers can be ordered directly from bitmain, but I do not see any product available on their site, you can in this case make use of their customer support for any solution.
Note: I have not ordered for any miners before, also you may like to use purchase Graphic cards for altcoins, but for Bitcoin ASIC are better, try out AliExpress.
