Ya  I  saw  that and i'm  being dead serious when i say  that I   thought of  this  md5 concept the morning  before  they  published  that  post but  anyways there idea i  believe  has  a higher  chance then my idea to  get a lower  amount then  what you deposit  while my  idea gives everyone  the same small  chance of losing, its  kinda like a lottery but  the lucky  number loses in this  case
