I think you need to check your hi-low game history. Is there anyone hack your system and they lost your money in the hi-low game. If you don't know how to check then you can write to admin and they can tell you what exactly happened in your account transactions. Did you enable your account 2fa function? If not better you enable it if you're planning to store some coins in your account.

Never happened to me and I am using freebitcoin for year and a half.
How did you lose it? Have you played hi-low?
You can send PM to owner here https://bitcointalk.org/index.php?action=profile;u=154142 and explain to him your problem.

is your problem get sorted? did you really lose 60k sats?
I'm bit worry now, just turned on pc... connect to internet... open freebitco.in
and when I try to login, I'm getting red notification
Too many tries. Please wait 5 minutes before trying again
is my account getting hacked or something? or am I connecting thru bad ip?

edit:
OK... I logged in just fine now, but that notification got me worried
because I just deposited some btc amount 3 days ago

is Myfe online only on weekend? my question still hasn't been answered yet.
and I have another question, if anyone can answer please don't hesitate
- is there a way (or legal trick) to auto withdraw (free) on sunday but only partial of my balance
I can see the slow & instant option, but I want the weekly free option withdraw
but leave certain amount of balance so I can play on multiply btc
