1. How does mining help you to earn more bitcoin?
2. And is this mining is the best way to earne more bitcoin?
1. It will you if you have a money lets say 50 thousand or more (example only) you need that to buy GPUs that will let mine. Like others told you and the user right here you need time half the year.
Mining gives profit if proper miners are used. If you decide to mine via your CPU then the only thing you will have at the end of month will be a few satoshi. If you use proper Miners you will get some profit after 6-7 months. Antminer L3+ is the most profitable untill now. You can purchase it to earn some good income. If you want to make more profit, you can setup a mining farm and start earning huge.
The cost of equipment for mining now soared to the moon. I very much doubt that you will get your money back in 6-7 months. Antminer price comes to $ 3,000. Prices of graphics cards 450-600 dollars. Do you think these costs will be repaid?
TAKE NOTE: that your electric bills will get high.
2. Its the best way if you really have the money ang have patience on mining. For me the sure win and best way a in a campaign you just need the requirments like in a blog post and article campaign social, media campaign and my favorite signature campaign.
Allof this campaign I told is just effort no wait cost of high electric bill and if your rank up really high you will earn big in the campaign that you will join.
