I read their communication channels before investing. In short, they've been mining crypto 7+ years and have a few data centers in different countries. They purchase mining equipment in bul for cheap, and have an electricity costs of just 0.05$ per kWh. So like 10-15 times cheaper than it would be to mine in US or Europe lol. That's how they have the best mining compared to any retail miner. Maybe better than some big mining companies too, especially if they're based in UK/EU/US. Seems like an only way to start mining BTC at this point, if I'm not a data center in 3rd world country myself.
