One of these two teams is putting on sunglasses today:

My sports bets are not only on football, I have to add proteins, vegetables, you know, a varied diet.

I don't want to touch my funds in my non custodial wallet so planned on making deposit through a CEX
Is it safe to make deposit via a CEX? And I found out that the address for Bep20 is same with ERC20 on the USDT network.
:://:://:
Is it a welcome back bonus for long term user or it applies to newly deposited account too?
And promised 180% of deposit above $10 is it given as the deposited network token or in BC.Games token?
I don't know exactly what you mean by the question "is it safe?", there are several ways to answer it, every deposit has its history, the trace, so it's the same when you withdraw from a casino to Cex, is it safe for your account in that centralized exchange to withdraw from any casino, there are exchanges that have very strict rules with that.
On the other hand, bc.game accepts most networks for deposits in usdt, I usually use Polygon, it's the most "economical".
As for the 180%, a wonder no? but did you read the fine print, Unlock amount = wager amount * 1% * 20%
