I go like know how e b wen una start una mining
Like no institute dey wey dey teach am so how una take grow una knowledge
Since I dey this forum I never really notice any Nigerian when dey mine bitcoin so most of the answer you'll receive here wii just be based on what they understand and not what they have experienced, but incase you're really interested in learning the in-to-to of mining then you probably should consider following the link provided by @Amphenomenon and ask question there although it won't be just mining in Nigeria alone but mining inn general.
I just find out say this forum dey since 2009, but why e nor popular? because me just find out this year
Most people discover about 'this forum' from a friend or someone close to them; however, only a small percentage of those who are truly interested in bitcoin find the site on their own. I'm not sure the category you fall into but I hope you get the knowledge that you seek.
Our light matter nor dey affect the mining machine?
I'm not sure how well electricity is supplied in your area, but if you're the type that receives constant electricity for more than 12 hours a day, it might not be a problem for you, but if you're the type that receives "two to four" hours light, it will be a huge hindrance for you unless you have another alternative to generate your own electricity to power your mining rig. Remember the cost of electricity also matters here.
if I wan start mining wetin go b d challenge wey I go face
Apart from electricity, the only obstacle you'll face is funds to purchase a mining machine. You should understand that you cannot mine bitcoin with any system. You've probably come across some website advertising that you can mine through their mining cloud by just paying a charge and leaving your PC connected to their server, but you can't.
To mine, you'll need to invest in some ASIC hardware.
I find out say many people here dey code abeg coding dey important to mine Bitcoin?
Don't be suprised when you find out that your claim is not totally correct as majority of people here don't really know how to coding most just know only the basic of some programming languages nothing more. And to your question, yes, you can mine without knowing how to coding.
