Better option for the Cloud Mining

I would not recommend Hashflare, they have a bad history and habits of changing their contracts when they want and how they want.
They just recently announced that they changing contracts to be limited to 1 year, instead of unlimited, with out even granting you any options to withdraw your money. I think Genesis Mining will be the better choice to invest.
If you want to get 3% discount on your purchase from Genesis Mining, use the code P1vkfa

However, my advise you only invest what you can lose. Cloud mining has a bad history.
