Currently I'm cloud mining on genesis-mining and I'm going to purchase a lifetime bitcoin gold contract for $350 dollars. So being a tad bit curious to see how much it would cost to do a custom bitcoin plan. When set to 2.5 TH it cost $349, while a 2,500 GH Platinum contract cost $350. Could someone please clarify why its cheaper to do a custom plan instead of purchasing a Platinum contract?
