From what I know, most crypto casinos require withdrawals to be made using the same coin that was deposited. But I'm not entirely sure if Vegabet works that way since it depends on how the platform handles the balance. So the suggestion to use BNB is actually a great idea, but it would work best if BNB is chosen from the very beginning before depositing. That's why checking the withdrawal fee before deciding which coin to deposit is really important, because once the deposit is made in Bitcoin there's no escaping those higher network fees when cashing out.
Exactly, almost all casino for withdrawing fund based on deposit coins kinds and I don't get any casino platform have exchange or swap feature at their casino for converting one coins to other coins. Important thing have to know avoid higher fees transaction before depositing coins check firstly feature of withdrawal fund which one coins have cheapest fees for withdrawing, deposit trough bitcoin actually has stable fees but price of bitcoin most expensive nowadays make its not worth gambling by using bitcoin fund.
Using altcoin is better way avoid from higher fees but if won't price of altcoin drop significant during at betting moment I think BNB, LTC good choose deposit to Vegabet account because both of kinds coins have lower fees for withdrawing.
