You should be worried about two things:

Any big win even if your account is overall loss in your account history.

If you have a winning account.


Other than that for NOW your money is safe but you never ever ever know with Cloudbet.

Besides this, why support this sportsbook knowing they take customer money.  If you are a losing account don't continue giving them your money.  Do not deposit.  You will be doing a service to the community if you help them not be in business any longer.  They steal.
