I know huge capital is required to meet up huge financial expectations, what's the minimum volume of income one can use to start mining? In a situations where you trade with different strategies and still hits wrong targets, if you apply or use same trading knowledge for mining won't one still loss in mining too? Because I don't have enough money with me, so am trying to cut losses if mining too will not favor me I will decided to venture into mining too again.
Can I start mining with $300 and grow from there?
Trading and mining are two different things and you need to have the proper knowledge and finance. Mining with $300 is impossible when you don't have your mining equipment,the equipment are expensive to set up compared to that amount that you mentioned. Electricity cost is also there,and you should understand that mining consumes more electricity. If you already have the equipment then it will be possible for you to use $300 to start mining. Don't also forget that mining is risky due to low profit and some miners do pack up their mining farms and quit from mining. Government new policy in a country that kicks against bitcoin will also affect mining activities in that country. These are all what you put into consideration before making up your mind.
