All the sportsbook with Betby odds provider is identical. You should have avoided Chips.gg if your account was limited on a different sportsbook where the odds provider was same. It is pretty clear that the decision has come from the odds provider to block your account. And Chips.gg team have decided to withhold all your funds, including the deposit (according to terms 13.1 from 'PM/Chat logs'). They should have allowed you to withdraw your deposited funds.
I made a withdrawal for 500 USDT 3 days ago, I'm still 100% I've made more deposits than withdrawals so they should refund my deposits if they have go by their terms.
As for the sportsbook thing, 80% of the casinos use Betby nowadays and only a little percentage of those have shady practices. I still have activate Betby accounts and as of now.
