The worst is "E0b0t" but luckily I only put in $10 to test out and it's so not worth if you sit & do nothing with the payouts! Every time it mines me 1 STEEM it automatically sends it off to my Steemit Acc. So, when STEEM reaches Big numbers(near future), it will be worth it! And again, I can trade that STEEM to make more STEEM if I choose as well.
