The price will go up because of the halving of the rewards BTC will become more valuable and more difficult to mine. The payouts on HashFlare are better because of reduced electrical fees and new miners. If someone wants to give a best offer thats fine with me
Besides being a huge ammount how would you do this sell directly with hashflare sending the hash to the buyer without any escrow between? What besides bitcoin can be mined with such hash, as bitcoin isnt maybe the best option to mine now, even with good rates.
