Black Arrow fraud

ba logoHere is the story about Black Arrow fraud company where I’m unfortunately the main participant.

As an ordinary IT guy I decided to try myself in the world of cryptocurency minining. In August 2013 I’ve bought a huge ATX motherboard with 4 PCI-e slots and expensive AMD video cards. The choice of concurrency for mining was BitCoin. I’ve registered with 50BTC pool and mined something about 1.2 coins until the 50BTC pool was hacked. Later on I’ve dropped all the video cards (somebody received a perfect present) and decided to buy a specific mining equipment for BTC.

During October 2013 I was browsing around the mining forums, trying to understand what is scam and what is real in the concurrency world. Majority suggestions on the market were absolute fraud websites which suggested various ideas to bump your pocket and to fool you in polite manner. So I’ve made up my mind and in December 2013 I’ve  ordered Bitcoin miner from Black Arrow fraud company, a model Prospero X-3  for $6000 USD. 

While you are reading this, I hope you are not one of these customers like me, who did the same order from Black Arrow fraud company, so I will not ruine your mood for the rest of the day.
