Storing cryptocurrency on centralized exchanges is not a good practice and if it comes to withdrawal fee, it will cost you more.
When already trading SHFL to USDT then withdrawing with the BSC network is much more or TRX which usually costs 1 TRX.
But so far I have never kept assets on the exchange for long, it is only an intermediary for exchanging coins to a cheaper network and using them again for gambling.
I don't like it when playing in casinos using ETH network coins because I can't withdraw small amounts, as for other coins then it's easier to withdraw even though the numbers are small.
I am guessing that's pocket money for some as people got some huge airdrops from here, but for rest of us, i can't figure out why they wouldn't have an option to trade it in arbitrum or other L2. Or maybe it's coming later and people with less money aren't high priority right now. Which i can understand as they live from whales. But if not Aribitrum, maybe a reputable CEX. Unlike those where it's currently listed.
Luckily this is not an exchange, so maybe you have faith to keep your tokens in longer. And it's not like we have an option to get it all out anyway, as most of it is still locked. I would definitely keep mine in before option to withdraw with L2. Price action will probably get more interesting at that point as there have been quite few burnings.
