With the market declining, it is not wise to gamble with BTC. Especially the transaction fee in using major crypto such as ETH and BTC. That is why gambling platforms with several alternatives such as XRP, DOGE, TRX and other alts is a good attraction for convenience.
But that is only true if you are holding altcoins like those, if you are only holding bitcoin like the majority of the people in the forum then if you want to gamble you have no option but to gamble with bitcoin, since it does not make sense to convert your bitcoin into altcoins since now you need to pay a transaction fee and pay a fee to the exchanges well and finally you will need to pay a transaction fee to transfer your coins to the casino, as such I do not see the point of forcing yourself to gamble with altcoins if you do not have them and you are only holding bitcoin at the moment.
