So far, most crypto casinos accept not only one crypto like Bitcoin or Ethereum only. They commonly will provide several options like both BTC and ETH, BNB, TRX, LTC, XRP, Doge, and maybe others. This is actually to ease the users in doing transactions. Moreover, it may also relate to the speed and transaction fees. As we know that Ethereum actually has very high fees. That is why there are other options available in most casinos.
transactions on Ethereum are still costly but bsc can be used for that. If any casino platform wants to allow its user to play without registration. Where players only need to connect their metamask wallet.
Yes, we may use the BSC network to get lower transaction fees when transferring ETH. But unfortunately, not all casinos provide the options. It is helpful if there are several options of the networks like BSC, but if there is, Ethereum really has higher fees to spend. and this always becomes the conisderation by many gamblers to use ETH actually. That is why they prefer to use other cryptocurrencies if available.
