No worries, I felt quite honored making this video because I knew at least someone will watch it and cares about my opinion. There is no reinvest option at Genesis Mining. It seems they simply sell the hashpower which they got or will have in the near future due to their calculation. From my point of view this approach makes sense to me. As far as I know the reinvest option at Hashflare doesn't make sense necessarily because all their contracts are limited in their duration. So re-investing is similar to purchasing a new contract. Re-investing won't extend the existing hashpower you bought previously.
