Hello.
Is there a proff that anyone ever roll 10000 ?

I am doing FreeBitco.in ~ 2 months and neither me or one from my 200+refs roll more then 9993

i have once rolled 9999 on dogecoin faucet,i can give you my screen if you want, also as i remember, there were one or two people who had rolled 10000.
anyway, continue trying and soon or later you will roll it

good luck
