i personlly like hashflare more than genesis-mining.

but both of them have made "mistakes"  (as far as ive read, please correct me if im wrong)

• genesis stoped mining (idk wich coin or what) when it was still profitable
  
• hashflare was build on a dummy person but now is an legit company
  

my hashflare setup is evenly between all pools

i cannot compare directly because i dont mine the same @ these sites.
may this can be answered by an more experienced user.

but ive never seen any real mining proof from hashflare neither genesis
so i dont really trust both of them, but they look way more legit than other sites that ive visited.
