Scammers are back with the old style of bitcoin mining scam giving you outrageous return in a short while. They claim to be using the fastest mining tool which they claim is Ant miner S9.
They promise to give you as much as $980 for an investment of $70 just in 12 hours. That is practically impossible to be real.
Let us all beware as the scammers are trying both new and old methods to ensure they dupe you of your hard earned fund.
You are very particular on the plan they are giving and the services and what kind of product, but you failed to give us the name of the Bitcoin mining sites that you are describing, no one's a fortune teller here and it's for the benefit of newbies as well.
