Pročitao sam zadnji blog. Nije loš, ali ja bi ga malo ipak prepravio. Evo samo jedne od sugestija:

If you are choosing cloud mining, you’re probably wandering: Hm, what to choose? Will I make profit?
So, I will help you which cloud mining to choose.
Let's see how much bitcoin cloud mining actually costs.

1. The price of 1 Th/s bitcoin cloud mining at:

Hashflare: $80 right now for 1 year contract.
Genesis mining: $180 right now for open-end mining contract (mining lasts as long as it is profitable).

2. Let's see if it is profitable:

For calculating profitability I use the site called  “whattomine.com”
1 Th/s per year will yield:
$228.72, without pool fee.

So it is profitable, but it is at your own risk due to the mining difficulty changes, bitcoin price etc.
