The ease of use, user friendly interface. And most importantly it's price! It makes sense to go for this service when looking into cloud bitcoin mining services. I have no complaints about my experience using them so far. They are very responsive and support team too. Their customer care representatives respond almost instantly and they're always willing to help out in anyway they can. If you want a hassle free service that gives great returns then try out BTC miner. Bitcoin Cloud Miner has been a life saver especially at times like these where crypto currency prices drop drastically. In those situations we were able to maintain our hashrate even though the market was down. The customer support team are very helpful, fast at replying emails when we have questions or need help! I love that they can take payments in multiple currencies (USD/EUR) which helps us immensely during times where our exchange rates aren't great but still want people using their service so it's not just USD only transactions for them - this has been really good since many customers don’t like paying via bank transfer sometimes due currency fluctuations etc..
